In this guide, we will delve into various types of tensioners, highlighting end accessories, installation, and applications.

What Are Tensioners?

Turnbuckles, also known as tensioners, cable tensioners, barrel tensioners, or adjusters, are devices used to adjust the tension or length of cables, ropes, tie rods, and other tensioning systems. They are crucial components in industries such as construction, oil and gas, maritime transport, mining, and fishing for securing or tensioning wires, cables, and rods. By twisting the body of the turnbuckle, you can extend or shorten the system to which it is connected without rotating the end fittings.

Tensioner Materials

Turnbuckles are mainly made of carbon steel or stainless steel. Carbon steel turnbuckles are usually galvanized to prevent rust and corrosion, while stainless steel turnbuckles are ideal for environments with high chloride content or moisture due to their superior corrosion resistance. In critical applications with a risk of corrosion, the use of stainless steel turnbuckles is recommended.

Tensioner End Accessories

Turnbuckles come in various types and sizes, with three crucial components: the body, a right-hand threaded end fitting, and a left-hand threaded end fitting. Turnbuckle bodies come in two main styles: closed bodies and open bodies. Different end fittings are available to adjust the tension of cables or ropes when connecting to anchor points. The main types of end fittings include:

• Hooked End: Ideal for temporary connections, the hook ends are easy to connect and disconnect from other components, but should be used with caution, as the absence of a safety lock can cause accidental disconnections.
• Fork End: Composed of a fork, a bolt, and a nut (or, in some cases, just a cotter pin), they connect directly to steel cable slings and lifting eyes. They offer a robust and secure connection.
• End with Eyelet: Designed for linear traction and non-lifting applications, this end, with no moving parts, can be used with shackles or quick links, aligning with wire rope slings for a secure connection.

By combining these ends, the stretchers can be customized to meet specific needs, ensuring a suitable type for permanent or temporary solutions.
