Consisting of a body and two end fittings - one right-hand threaded and one left-hand threaded - turnbuckles are a valuable tool for anyone working with wire rope.

You simply connect the end fittings to the guy wire end or a securement point, then turn the body of the turnbuckle to adjust the tension. Since each end fitting has a different thread direction, turning the body will tighten both sides.

The jaw & jaw turnbuckles are designed to work with closed hardware, such as an eye. You can remove the nut/pin and the bolt, connect the jaw to the hardware, and then secure the bolt again.

Jaw & eye turnbuckles have two different end fittings. One is a jaw, and the other is an eye. The eye will connect with shackles and other hardware that can open.

Both the jaw & jaw and jaw & eye turnbuckles from Van Beest are high-quality and European-made. They are made from drop-forged, high-tensile steel SAE 1035 or 1045.

Crosby® guy wire turnbuckles (both the jaw & eye and jaw & jaw) are made in the USA. They meet or exceed all requirements of ASME B30.26, as well as other critical performance requirements like fatigue life and impact properties.

A turnbuckle also is known as rigging screw, tensioner, straining screw, barrel strainer, or adjuster, is a device for adding or releasing the tension or length of ropes, cables, tie rods, and other tensioning systems. They are used for rigging or tensioning wires, ropes, rods, etc., typically within industries such as oil and gas, construction, shipping, mining, and fishing. You can easily twist the turnbuckle body to expand or contract the length, without rotating the end fittings on both sides.

The most common turnbuckle materials are carbon steel and stainless steel. We usually add a zinc layer on the carbon steel galvanized turnbuckles with protection against rust and corrosion, while stainless steel turnbuckles can be used in high chloride or high moisture environments, as they offer a higher level of corrosion protection. If corrosion is a concern, stainless steel turnbuckle is your best choice.

Rigging turnbuckles are available in many different types, sizes, but basically there are three primary turnbuckle accessories: a turnbuckle body, a right-hand threaded end fitting, and a left-hand threaded end fitting.

Hook end – are used for temporary connections and are much easier to install and attached or detached from other rigging components than jaw end turnbuckle and eye to eye turnbuckle. However, it is far less practical due to the lack of a safety latch, which may unexpectedly release from attached rigging components, cause the hook to dislodge.

Jaw end – are composed of a jaw, bolt, and nut, but depending on size, some jaw turnbuckles only come with a cotter and a pin. They can attach the wire rope sling straight onto the jaw end and pin to the lifting eye bolts and lugs, which cannot be opened.

Eye end – are intended for straight-line pulls only or in-line applications not for lifting purposes. They have no moving and opening parts, designed for a shackle or quick link to go through on each eye end, then attached a wire rope sling or other approved rigging components.

The turnbuckle ends can be combined according to different needs that whether the solution is permanent or temporary, so there are many different types of turnbuckles.

Turnbuckles are used for adjusting tension in ropes, cables, tie rods and other tensioning systems, as well as for pulling together and pushing apart anchor points. Heavy duty rigging turnbuckles consist of two threaded bolts, each screwed into the ends of a metal frame. One side is left-hand threaded and the other is right-hand threaded, so riggers can turn the metal frame to push apart and pull together the threaded bolts. These threaded bolts come with a wide variety of end fittings and attachments including jaws, eyes, clevises, hooks and many more. All cable turnbuckles and turnbuckle hardware feature UNC threads so you can change out end fittings and bodies as needed.

Whether you are using a small turnbuckle or a large turnbuckle, they should be used for straight or inline pulling, and tensioning only. At Tri-State Rigging Equipment we pride ourselves on providing our customers with only the highest quality industrial turnbuckles and turnbuckle hardware, from only the most reputable manufacturers. If you are unable to find what you are looking for, or if you don’t know exactly what you need, call or email our sales team to speak with a rigging product specialist.

Turnbuckles are very popular in the marine rigging industry, where corrosion resistance is often the name of the game. Stainless steel offers the most corrosion resistance but can be expensive. On the other hand, galvanized steel is more economical, but less corrosion resistant. Brass turnbuckles are the ideal solution for applications that require explosion and spark resistance. Aluminum turnbuckles lead the industry in light weight and low-cost design.

Our heavy-duty stainless-steel turnbuckles can also be equipped with an enclosure, called a pipe, covering the threads and body of the cable turnbuckle. Sometimes referred to as a closed body turnbuckle, this option is very popular in the architecture industry where cosmetics are a top priority.

The most basic turnbuckle fitting, threaded rod turnbuckle fittings are simply a steel rod with standard threads on the end that can be easily connected to a post or other mounting surface.

An eye is a solid loop end, mainly used with wire rope. The solid construction of turnbuckle eyes ensures that there is no way for the wire rope to slip through. Elongated eyes are not only good for reducing stress on the turnbuckle hardware, but they also make it easier to connect to marine rigging equipment.

When you have a fixed anchor point or the anchor point must be secured from slipping off the fitting, fork or jaw turnbuckles are a perfect solution. A fork or jaw is a wishbone shaped anchor point secured by a nut and bolt, or pin and cotter.

Hooks offer the quickest attachment and release when it comes to turnbuckle hardware. Hooks are very versatile and can be an ideal option for a wide variety of turnbuckle applications. A cable turnbuckle with two hook fittings, called a hook and hook turnbuckle, can have hooks that open the same way or hooks that open opposite ways depending on what you need for your specific rigging application.

A deck toggle is a mounting bracket around a “T” shaped bar. This allows the turnbuckle to be securely mounted on one end and able to be rotated 180° parallel with the mounting bracket. Deck toggle turnbuckles are most attached to deck posts.

Drop pin turnbuckle fittings consist of a pin that can be flipped flat into the body of the threaded bolt and can also be flipped out at a 90° angle from the threaded bolt. This allows the bolt to be threaded through a hole while the pin is flipped in and then securely held in place while flipped out.

Stub end turnbuckle fittings are not used to attach to anchor points like other turnbuckle hardware, but rather, are used to separate or push objects apart.

Swage stud turnbuckle fittings are used to seamlessly connect a turnbuckle to the end of a wire rope. Swage stud turnbuckle fittings are threaded to accept wire rope wires directly into the fitting, and to be swaged for a secure attachment between the wire rope and the turnbuckle.

Rigging turnbuckle hardware and assemblies are extremely versatile and can be configured in countless combinations to fit any rigging application. Some of the most popular configurations include:

These are only a fraction of the combinations that are possible when configuring a rigging turnbuckle. Even better than the near limitless combinations of fittings, however, is the interchangeability of turnbuckle hardware. For example, to change a jaw and jaw turnbuckle into a jaw and hook turnbuckle, all you need to do is unscrew one jaw fitting and screw in a hook fitting. This top tier customizability and interchangeability is why heavy-duty industrial turnbuckles are an extremely valuable part of any rigging operation.

Tri-State Rigging Equipment is a service provider and distributor for all heavy duty industrial turnbuckles for rigging and lifting; serving clients from coast to coast, Canada, Mexico and especially focused in the states of Missouri, Illinois, Indiana, Iowa, Kansas, Nebraska, Arkansas, Mississippi, Tennessee, Kentucky, South Carolina, Florida, and Oklahoma.

Turnbuckles are a diverse product line that are used in a variety of applications across many different industries. They can be used in applications as simple as providing tension in a fence or perimeter cable, or something as complicated as the construction of a suspension bridge.

Like other rigging hardware products, turnbuckles are available in many different sizes, configurations, and types. We realize that there aren’t a lot of available resources out there to educate you on turnbuckles, especially if you aren’t already familiar with them.

With this article, our goal is to help you form a base-level understanding of turnbuckles, how they work, and how they can be properly utilized during your next project. In this article, you’ll find basic information about:What a turnbuckle is

The end fitting on either side of a turnbuckle connects to the tensioning system and/or a securement point. The turnbuckle is then tightened or loosened to adjust tension and eliminate slack in the cable or rope is it connected to.

Body: the metal frame in the center of the device that joins the two threaded end fittings. The body itself is turned to adjust tension by extending and retracting the end fittings.

The body may be one of two types: closed or open. An open body turnbuckle is the more traditional type where the threads are visible through the body frame. Closed body turnbuckles—also known as pipe bodies—encase the threads in a closed frame to create a slimmer profile that fits in tighter spaces.

End Fittings: these are the two connection points that screw into the opposite ends of the turnbuckle body. One end fitting is right-hand threaded while the other is left-hand threaded. This allows you to turn the body to adjust tension after installation without moving the end fittings.

There are three main types of end fittings that can be used together in any combination on either end of the turnbuckle:Hook end – a hook end fitting is used to create temporary connections because they are easy to quickly connect and disconnect. They should never be used in connections where tension could unexpectedly release.

Thread diameter: this is the diameter measurement of the threaded portion of the end fittings. The greater the thread diameter is, the greater the load-bearing capacity of the turnbuckle and vice versa.

Turnbuckle types are, essentially, named for the combination of end fittings used in the device. The most common end fitting combinations are:Jaw and jaw

As you might have guessed, an eye and eye turnbuckle has an eye end fitting on either end. Likewise, a hook and eye turnbuckle has a hook end fitting on one end and an eye end fitting on the other.

As mentioned above, turnbuckles can be used with a length of rope, cable, or other rigging assembly as a connection point to adjust slack and tension within the line.

Turnbuckles can be used for something as simple as a fence or as complicated as a suspension bridge. Some industries that commonly use turnbuckles are:Sports and entertainment – turnbuckles are used to act as a securement point and to create tension in the ropes surrounding a wrestling or boxing ring. You can’t see them, of course, since they are covered in soft material for the athletes’ safety!

Proper installation of any type of rigging equipment is essential to maintaining safe and effective applications—turnbuckles are no different. Installing a turnbuckle is a rather straightforward process, here are the steps:Unscrew end fittings from the body until completely extended to the full take-up length

The most common turnbuckle materials are galvanized and stainless steel. Choosing between these two materials is important if factors like price and corrosion resistance are important to you.

Stainless steel turnbuckles are ideal for use in outdoor and saltwater environments, as they are extremely resistant to rust and corrosion. If corrosion is a concern, stainless steel is likely the best choice for your turnbuckle material.

Galvanized steel turnbuckles are cheaper than stainless steel and can also be used in outdoor applications, but with caution, as they are not as resistant to corrosion as stainless steel turnbuckles.

During the course of a turnbuckle inspection, remove it from service if any of the conditions listed in ASME B30.26 – Rigging Hardware are present:Missing or illegible identification

We hope that the information laid out in this article helps you to understand what turnbuckles are, how they function, and whether they can be applied to your rigging assemblies.

While turnbuckles are relatively simple when it comes to mechanics, they can be used to apply tension and eliminate slack in virtually any tensioning system.

Here are some factors to consider when determining the proper turnbuckle type and configuration that is best for you:The three main types of end fittings can be combined in any configuration to allow the turnbuckle to attach to open, closed, temporary, or permanent connection points.

At Mazzella, we stock and distribute turnbuckles in a variety of different configurations and sizes in both galvanized and stainless steel. Our turnbuckles and turnbuckle parts are manufactured by premium vendors, including Crosby and Suncor Stainless.

We partner with all the major rigging hardware suppliers in the industry. We stock and distribute a full line of turnbuckles from several manufacturers, including:Crosby

A mere two miles down W Indiantown Rd from Marsh Fasteners, you will find them in a local boxing club. Three miles in another direction, and turnbuckles abound at Admiral’s Cove Marina. Heading further south on Interstate 95, turnbuckles can be found in highway guardrails. Arriving at Palm Beach International Airport, you will find them regulating the tension in aircraft cables and wires.

Whenever you need to gradually adjust the slack within a tensioning assembly, these handy rigging devices will be used. Also known asbottlescrews, the threaded metal couplings are used to connect and increase or decrease the length of ropes, tie rods, cable lines, and so on.

As with other fasteners, turnbuckles come in different variations in length, size, type, and configuration - each suitable for specific uses. There are three parts that make up a typical turnbuckle:One rectangular body that has holes on either end – one side with right hand internal threads and the other with left hand internal threads.Body sizes range in length from about two inches to over 12 inches. However, turnbuckles are measured by the length of their “window”, or take-up inside the body, rather than their entire length.

Instances where turnbuckles are used dictate that they must be able to withstand high forces without breaking. For that reason, most turnbuckles are made of galvanized or stainless steel. The type you choose will be determined by the factors that are most important to your assembly:Galvanized steel turnbuckles are the cheaper of the two materials. Although they can be used outdoors, they are not nearly as corrosion resistant as their stainless steel counterparts.

Stainless steel turnbuckles are extremely resistant to rust and other forms of corrosion. This higher level of corrosion protection makes them a superior choice for outdoor applications and high moisture, high chloride, and saltwater environments. Bear in mind that demanding marine and coastal conditions require high-quality 316 grade stainless steel for safe and prolonged use.

Because the threads of the holes on the body go in opposite directions, the inserts also move in opposite directions so that:When the end fittings are screwed in and the body is rotated in one direction, the inserts are both pushed out of the body, extending to relieve tension on whatever section of rope or cable they"re attached to.

The amount of tension applied depends on how far apart those two nuts are when they are attached (known as "closed") and what type of material makes up your particular turnbuckle.

Because the body of a turnbuckle is rotated to expand and contract its length, the end fittings remain stationary. That is how turnbuckles are designed to make it easy for you to loosen or tighten strapping et. cetera without twisting the tether.

A turnbuckle may be used to adjust the tension in an assembly in extremely fine increments. At the same time, each of the inserts is just less than half the length of the turnbuckle’s body – allowing for an adjustment of almost the full length of the body.

The threading on turnbuckles allows them to be tightened and loosened without the use of tools, making them popular for quick adjustments in the field.

The installation of any sort of rigging equipment must be correctly done to ensure its safe and effective use, and turnbuckles are no different. As turnbuckles are used to control the amount of tension on a wire or rope, they can be hazardous if used improperly.

To ensure that all rigging is properly installed, follow these four easy steps to instal a turnbuckle:Unscrew the end fittings from the body until they are fully extended to their maximum take-up length.

A hook is simply connected to a point via a shackle or a quick link, while an eye is connected to a point via a shackle or a thimble. The jaw is unscrewed and the bolt is put through the clevis ears and screwed shut.Turn the turnbuckle to draw the ends together until the rope or cable is sufficiently tight.

Before removing a turnbuckle connection from a cable or rope, the tension must be entirely released, leaving some slack in the line. Otherwise, the cable or rope may fly around as the tension is suddenly released.

Turnbuckles that have been distorted due to the pressure and tension they"ve been under should not be reshaped using heat, as this will reduce their durability.

Turnbuckles act as tensioning devices that enable users to easily adjust the tension within cable lines associated with both mechanical and c applications. As such, they are frequently used in the construction, mining, oil and gas, fishing, and shipping industries.

Selecting and using the right device is important to maintaining a safe and effective project. Since 1992 Marsh Fasteners has been helping you choose the right type of turnbuckle for each application, and even decide if you should be using a turnbuckle at all.

Rigging screws, barrel strainers, bottle screws, tensioners, straining screws, or adjusters… call them what you will! But whenever you need 316 grade stainless steel turnbuckles, the experts at Marsh Fasteners will be able to guide your selection and supply top quality products. Contact us today.

The most common turnbuckle types are: eye and eye, hook and hook, jaw and jaw, jaw and eye, and hook and eye, each named for their combination of end fittings. The fittings are determined by what the turnbuckles need to connect to and whether the solution is permanent or temporary.

Eye and Eye:The eye and eye configuration is designed with a closed-loop teardrop fitting on each end. It’s the most frequently rented and may be used nearly anywhere. The eye and eye turnbuckle is intended for a shackle to be attached on each end, with the shackle pins going through the turnbuckle eyes.

Hook and Hook:The hook end fitting is commonly used to create temporary connections because they are easy to quickly connect and disconnect. However, since the hook configurations lack a safety latch, you should never use them in connections where the tension could unexpectedly release.

Jaw and Jaw:A jaw end fitting consists of a U-shaped jaw and bolt secured together by a nut or pin. This configuration offers the option to join the sling or lifting lug directly to the turnbuckle. In addition, it works well to connect components that cannot open, such as an eye bolt.

As previously mentioned, one useful application for turnbuckles is to make adjustments to help equalize a load and to correct an offset center of gravity. For example, if you needed to have 10 ft 7 ½ inches of total running length but didn’t have a sling of suitable size you could install a turnbuckle to accommodate for the difference by simply adjusting the turnbuckle in or out to get the desired length required for a perfectly level lift.

*Note: When adjusting turnbuckles, we recommend using an appropriately sized wrench instead of a spud wrench or pry bar placed through the body. The latter tends to cause damage to the turnbuckle and could potentially create dangerous repercussions. *

Another use for turnbuckles is when a lift has six vertical pick points, which may require a minimum four-bar system. Any time this situation presents itself, it becomes difficult to ensure you have equal load distribution among the six points. You have the option to place a sling on each of the four outside corners, which means on the two middle lugs, you can place another bar and utilize a shorter sling with a turnbuckle. This will allow you to adjust the tension to achieve equilibrium across all six lugs.

Proper installation of any piece of equipment is essential to maintaining safe and efficient applications and turnbuckles are no exception. After determining the WLL of the turnbuckle is sufficient for your application, follow these steps for installation:

As you know, turnbuckles control the tension between cables or wire ropes. Additionally, a turnbuckle helps rigging and hoisting crews reduce excess slack in the cables. There are several different types of turnbuckles to help crews work safely and efficiently. If you’d like to learn about your options when choosing a turnbuckle, we’ve got you covered in our guide below.

One of the most common types of turnbuckles is eye-to-eye. This turnbuckle features a ring-like end on both sides that easily attaches to other components such as a shackle. The main advantage of eye/eye turnbuckles is their security. If you’re performing a lift where you’re concerned the anchor may slip, you should use an eye/eye turnbuckle because it eradicates the possibility of slippage.

As you might suspect, the hook/eye turnbuckle has an eye on one end and a hook on the other. The benefit of a hook/eye turnbuckle is the fact that you can easily attach and detach the turnbuckle by merely reducing the tension on the cables. You should never use a hook/eye turnbuckle in scenarios where the tension could suddenly loosen because the hook could come out of place.

When you have guaranteed control, a hook/hook turnbuckle is acceptable. However, you shouldn’t use this turnbuckle for lifting because there is a risk the hardware may slip out of the hook. Hook/hook turnbuckles are most common for support or to adjust the length of a cable or rope. Because a hook/hook turnbuckle is so versatile, every company should have one in their collection.

A jaw-to-eye turnbuckle is common because of the jaw’s versatility. A jaw is a u-shaped end with a nut and bolt so you can easily attach it to other components you can’t open, like an eye. The jaw/eye turnbuckle is common because the jaw end provides added security with the nut and bolt on one side and the reliability of an eye on the other.

Unsurprisingly, the jaw/jaw turnbuckle has a jaw on each end, which allows you to attach your turnbuckle to the most unusual items. Moreover, the jaw/jaw can provide equal tension easily because the nut and bolt allow the turnbuckle to pivot as needed. Both a jaw-to-eye and jaw-to-jaw turnbuckle should be in your arsenal.

While these five different types of turnbuckles are the most common, we offer a variety of others, including deck toggle hand swage and a toggle swage turnbuckle. The most important aspect of cable rigging hardware is quality. When you’re lifting extremely heavy materials, you need to ensure your hardware can handle it. That’s where we come in.

Samco’s Turnbuckles / Eyeboltscome in a range of sizes and types. We offer Hook & Eye, Jaw & Jaw, Eye & Eye, Hook & Hook, Jaw & Eye, and Stubs End Turnbuckles. Turnbuckles are devices used to adjust the tension and/or length of such things as cables, tie rods, ropes and other tensioning systems. The tension is adjusted by rotating the frame, which in turn causes both eyelets of the turnbuckle to be screwed in or out simultaneously, without twisting the eyelets or the attached tensioning system (e.g. cable or rope).

Turnbuckles are used in industrial and other applications that required a large amount of tension. They can range in mass from a few grams for thin cable wiring to thousands of kilograms for large-scale structural elements found in suspension bridges and in buildings. Other uses include aircraft, shipping, and pipe systems to name a few. Turnbuckles are often used in conjunction with an eyebolt. Samco sells a wide range of eyebolts that include Regular Eye Bolts, Machine Shoulder Eye Bolts, Eye Nuts, and Shouldered Eye Bolts.
