turnbuckle tension wire rope with eye hook quotation

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 load rated rigging hardware used to shorten or expand wire rope and chain assemblies in the field. Turnbuckle configurations include Hook and Hook, Hook and Eye, Eye and Eye, Jaw and Eye, Jaw and Jaw, and Stud End combinations. All come Hot Dip Galvanized, quenched and tempered or normalized, and have enhanced impact properties for greater toughness at all temperatures.

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.

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.

Hook Eye Open Turnbuckle Forged Zinc Plated Steel Commercialis a turnbuckle also known as a Hook Eye Frame Tensioner. This fitting has an open body providing a rustic or industrial appearance for that timeless look. They are ideal fasteners for projects requiring tensioners or turnbuckles for galvanised steel wire rope. The welded eye at one end makes these fasteners extremely secure once installed. Additionally, the open hook at the other end allows for easy installation. Combined, these ends are compatible with a variety of fastening fittings, including screw eyes, eye bolts, and saddles.

Usage:The Hook Eye Open Turnbuckle will work in a range of sizes. The welded eye fastens securely to an anchor post or fork. Generally, the Hook Eye Open Turnbuckles work with terminal loops formed with ferrules and thimbles. A manual hand swager crimps the ferrule to the appropriate diameter of wire rope. This tensioner has both right-hand and left-hand threads. The body of the Hook Eye Open Turnbuckle can easily provide tension to your wire rope, without bending or stretching the wire. Tighten the body of the Open Turnbuckle by rotating the body until tensioned to your needs.

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.

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.

Hook and Eye : Similar to hook and hook, the only difference in this configuration is that the eye end allows for one secure end attached to the rigging hardware.

Jaw and Eye:The jaw and eye configuration is nearly the same as the eye and eye configuration, with the added flexibility to directly connect to the lifting lug. This configuration isn’t as common unless you have a fixed point or a lug that’s difficult to work on a lift.

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:

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.

Jaw end – a jaw end fitting consists of a jaw and bolt secured together by a nut or a pin. These are used to connect to components that cannot be opened, such as an eye bolt.

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.

A hook is used to attach to temporary connection points that may be frequently connected and disconnected. A jaw is used to attach to a connection point that does not open, such as an eye bolt or link. An eye is used to attach to a connection point that can open such as a shackle or quick link.

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

Connect end fittings on either end to desired securement pointFor an eye end fitting, simply loop it through whatever securement point it will be connected to (shackle, quick link, etc.)

For a jaw end fitting, unscrew the bolt from the jaw, place the securement point between the clevis ears (thimble, eye bolt, etc), place the bolt through, and screw it shut.

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.
