The body is the center of every turnbuckle assembly. It is the threaded frame that accepts the end fittings on each end and does the work of drawing them in when you turn it. If the existing body in an assembly is bent, cracked, or the threads are gone, the body is what gets replaced. Holloway Houston stocks Crosby HG-2510 turnbuckle bodies in 29 size combinations - thread sizes from 5/16 inch to 2-3/4 inch with take-up lengths from 4.5 inches to 24 inches and working load limits from 800 lbs to 75,000 lbs. If you are building a custom eye-jaw assembly or replacing a frame in an existing turnbuckle, these are the bodies to order.

Turnbuckle Bodies for Custom and Replacement Assemblies

A turnbuckle body - also called a frame - is the central threaded component of the turnbuckle assembly. One end has a right-hand thread; the other has a left-hand thread. When the body is rotated, matched end fittings threaded into each end draw inward simultaneously, taking up slack and applying tension to the assembly without rotating the lines connected to the end fittings.

Bodies are governed by ASME B30.26 (Rigging Hardware) and federal specification FF-T-791b, which cover design, materials, proof testing, and marking requirements. The body's rated WLL is marked on the frame per ASME B30.26.

Bodies are stocked separately for two main uses: building custom assemblies with specific end fitting combinations (eye-jaw, for example, where a complete pre-assembled unit is not stocked) and replacing damaged frames in existing turnbuckle assemblies while retaining the serviceable end fittings. Holloway Houston carries Crosby HG-2510 bodies in 29 size combinations across the full thread size range.

Crosby HG-2510 Turnbuckle Body

HG-2510 Specifications and Size Range

The Crosby HG-2510 is the standard turnbuckle body, forged and heat-treated, proof-tested, and individually marked with the WLL per ASME B30.26 and FF-T-791b. The HG-2510 body accepts Crosby jaw ends (HG-4037) and eye ends in matching thread sizes to build complete assemblies.

Holloway Houston stocks HG-2510 bodies in 29 size combinations:

Thread and Body Design

HG-2510 bodies are made with one right-hand threaded end and one left-hand threaded end in the same nominal thread diameter. The body's central frame provides the adjustment travel - the take-up length. Rotating the body clockwise draws both ends inward; counterclockwise releases them. End fittings are not included with the body; they are ordered separately from the jaw end or eye end category.

Using HG-2510 Bodies for Custom Assemblies

The HG-2510 body is the starting point for custom turnbuckle configurations. Pair an HG-2510 body with one Crosby eye end and one Crosby HG-4037 jaw end in matching thread sizes to build an eye-jaw assembly. Pair with two jaw ends for jaw-jaw. Pair with two eye ends for eye-eye. The complete Crosby HG-226, HG-228, and mixed configurations all use the same body at the rated thread size - the end fitting is what changes.

• 2-1/2" x 24" - 60,000 lbs WLL

Take-Up Length Guide

Shorter take-up lengths (4.5" to 6") give less adjustment range but a more compact assembly footprint. Longer take-up lengths (12" to 24") provide more slack removal capacity and greater future adjustment margin. The WLL at a given thread size does not change with take-up length.

Materials

• Crosby HG-2510: Forged alloy steel, heat-treated, hot-dip galvanized

Brands We Carry

Holloway Houston is an authorized Crosby distributor. The Crosby HG-2510 is the primary turnbuckle body in the Holloway Houston catalog - forged, proof-tested, and individually marked per ASME B30.26 and FF-T-791b.

Crosby bodies are the same frames used in the HG-226 eye-eye and HG-228 jaw-jaw complete assemblies. Stocking bodies separately allows Holloway Houston customers to build custom end fitting combinations or source replacement bodies without replacing serviceable end fittings.

Selecting a Turnbuckle Body

Selecting the right body starts with three parameters: thread size (sets WLL), take-up length (sets adjustment range), and the end fitting type you will pair with the body.

Thread Size and WLL

The thread diameter is the primary capacity determinant. A 5/8-inch body rates at 3,500 lbs. A 1-inch body rates at 10,000 lbs. A 1-1/2-inch body rates at 21,400 lbs. Match the body thread size to the rated WLL the assembly calls for.

Take-Up Length

The take-up sets how much adjustment travel is available. At the 1-inch thread size, bodies are available in 6-inch, 12-inch, 18-inch, and 24-inch take-up lengths. The WLL is the same across all take-up lengths at the same thread size - the longer body simply provides more adjustment range.

End Fitting Compatibility

Crosby HG-4037 jaw ends and matched Crosby eye ends thread into the HG-2510 body in the same nominal thread size. The body thread size corresponds to the end fitting thread size. RH jaw ends thread into the right-hand thread end of the body; LH jaw ends thread into the left-hand thread end.

Replacement vs. New Build

For replacement applications, measure the thread diameter on the existing body before ordering. The take-up length is measured as the distance between the thread engagement points on the existing frame. For new builds, the thread size follows from the required WLL and the end fitting sizes already in the assembly.

Turnbuckle Body Safety and Awareness

Turnbuckle bodies are load-bearing rigging components governed by ASME B30.26 and FF-T-791b. OSHA 29 CFR 1926.251 applies to rigging hardware on construction sites. The following awareness points apply:

• Crosby HG-2510 bodies are individually marked with the WLL per ASME B30.26. The marked WLL applies to the complete assembly in straight in-line tension. The body WLL and the end fitting WLL are matched - do not use a body with an end fitting of lower rated capacity.
• Visual inspection of the body before each use is standard practice. Cracks, deformation, bent frames, corrosion, and thread damage are the primary inspection points. A bent body, cracked frame, or damaged thread is a removal-from-service indicator. Thread damage that prevents smooth end fitting engagement is also a removal indicator.
• End fitting thread engagement - the number of threads engaged between the end fitting and the body - is addressed in Crosby manufacturer documentation. Minimum engagement requirements apply.
• Welding, heat-treating, or reshaping the body voids the manufacturer's rated WLL.
• After tensioning the assembly, locking the body in place is standard practice per FF-T-791b in structural applications. Wire-locking, jam nuts, or other methods are specified in the assembly design documentation.
• Proof test certificates and material certifications are provided with every Holloway Houston shipment of Crosby HG-2510 bodies.
