Stainless Steel Turnbuckles

Choose stainless steel turnbuckles for marine rigging, cable railing, lifelines and architectural tensioning systems. This section is organized into Complete Turnbuckles, Swage Turnbuckles and Turnbuckle Components so you can begin with the type of assembly you need.

Complete turnbuckles include common jaw, eye, hook, toggle and stub combinations in open-body, closed-body, forged and fully threaded designs. Swage turnbuckles connect directly to wire rope or cable. Individual components include bodies, jaws, eyes, hooks, toggles, stubs and threaded studs for building or repairing a compatible assembly.

Use the Turnbuckle Finder below to compare connection type, body style and thread direction. A working assembly normally uses one right-hand threaded end and one left-hand threaded end so rotating the body changes tension without twisting the cable. Always confirm thread size, material, end-fitting compatibility and the product’s published load information before ordering or installation.

Turnbuckle Terms & FAQ

What is a turnbuckle?

A turnbuckle is an adjustable tensioning assembly. Rotating its body draws the two threaded ends together or moves them apart to tension or adjust wire rope, cable or connected hardware.

What is the difference between a jaw, eye, hook and toggle?

A jaw uses a removable pin between two cheeks. An eye is a closed loop for a compatible pin or shackle. A hook allows quick attachment but is less captive than a jaw or eye. A toggle is a pivoting end fitting that helps accommodate angular alignment.

What are stubs and threaded studs?

Stubs and studs provide threaded or fixed mounting ends instead of a jaw, eye or hook. Their thread, diameter, length and mounting method must match the body and the installation.

What is a swage turnbuckle?

A swage turnbuckle has an end fitting that is permanently compressed onto wire rope or cable. Match it to the exact cable diameter and construction, and use the specified swaging tool and procedure.

What is the difference between open-body and closed-body turnbuckles?

An open body exposes the threaded ends and makes visual inspection straightforward. A closed body encloses more of the threads for a compact appearance and reduced snagging. Selection also depends on adjustment range, dimensions and load requirements.

Why do left-hand and right-hand threads matter?

A standard turnbuckle normally uses one left-hand threaded end and one right-hand threaded end. This lets the body move both ends simultaneously without twisting the cable. The thread size and direction must match the body.

Can I mix turnbuckle components from different families?

Only when the thread standard, diameter, direction, material, dimensions and published specifications are confirmed compatible. Similar-looking components are not automatically interchangeable.

How do I choose the correct size?

Start with the required connection types, cable or wire-rope diameter, thread size and adjustment range. Then verify pin, jaw or eye dimensions, material, installation geometry and the product’s published working-load information.
