Note:There are three ways to specify the callout of the turnbuckles your application requires. Most common is, for example, 1/2 x 6, where “1/2” signifies the thread size, and “6” signifies the take up, or how much thread length is useable for adjustment. Instead of specifying take up, turnbuckles can also be specified by “open length,” where the turnbuckle ends are fully extended; or, “closed length,” where the ends are turned fully into the body.

Before the installation of any type of turnbuckle hardware, it is important to know the right and left thread and the Working Load Limit (WLL), click here for more knowledge of M.B.S & W.L.L. By common convention, most threads are the default for right-handed screw threads. Therefore, most threaded parts and fasteners have right-handed threads.

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.

The rigging andindustry use lots of unique pieces of hardware that are not used for many other purposes. One such piece is the turnbuckle – soexactly and what is its purpose?

A turnbuckle (also sometimes called a stretching screw or bottlescrew)as “A device for adjusting the tension or length of ropes, cables, tie rods, and other tensioning systems.” While this hardware piece is relatively small, it can be used for large apparatus setups and can withstand weights up to 75,000 lbs.

Since itsinvention in the 1950s,the turnbuckle design has not altered very much. But there are many different types, designs, and sizes offered by– so it’s important to understand this information when purchasing turnbuckles.

The turnbuckle is made of three key parts: the body, jam nut, and end fittings. These parts may be made of different designs or materials, so knowing the names and purpose of each component is quite important.

The bodyis the metal frame in the middle of the turnbuckle. This is the part that turns so the end pieces on either side will either extend or retract. This is what creates the tension.

A turnbuckle’s body may either be open or closed. The open body design exposes the threads of the end fittings, making it easier to see how far the turnbuckle is extended. A closed body turnbuckle (also called pipe body) encloses the threads. This adds slightly more support and a smaller frame that is ideal for smaller fits.

There are two end fittings on either side of the turnbuckle. These serve as the connection point for the rigging equipment. There are several styles of end fittings that can be used, depending on the application. These components can also be mixed and matched – both end fittings do not necessarily need to match.

There are several types of turnbuckles. The primary difference is the end-fitting combinations. As mentioned before, the end fittings do not necessarily need to match.

Turnbuckles may also be made of different materials, depending on the application.are the most heavy-duty, as this metal is naturally corrosion resistant.would be recommended for applications exposed to the elements, such as for marine rigging.

The primary purpose of the turnbuckle is to easily adjust the tension within a rigging assembly. This can be used for simple setups like fences or boxing rings as well as large projects such as suspension bridges and aircraft.

The most important element of a turnbuckle is the quality of its material and construction. Since this small piece of hardware is responsible for securing heavy loads, it must withstand tension and weight without warping or loosening. The material requires durability to withstand external factors like moisture levels, direct sunlight, temperature fluctuations, and weight load changes.

Apart from the question ofwhat is a turnbuckle”, perhaps the most common one asked by our customers is how to install this piece of equipment. Proper installation is crucial – but thankfully, it is also fairly simple.

First, you will unscrew each end fitting to the full take-up length. Then each end fitting will be connected to the intended securement point. Next, you will rotate the turnbuckle so that each end fitting move in closer together in the center. This will create tension and become more difficult until you reach the desired tension. The final step is to tighten the nuts around each end fitting to the body for added securement.

It is important to note that turnbuckles must be inspected before use and any wear or damage requires replacement. If any parts appear corroded, rusted or damaged, the turnbuckle should not be used.

Choosing top-qualitypieces should be a top priority for any application. This includes everything from larger setups to small pieces of hardware, such as turnbuckles. These comparatively small components are responsible for providing necessary tension and holding large applications in place.

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.
