Crosby Turnbuckles

About Crosby Turnbuckles

A turnbuckle body connects two threaded end fittings, one right-hand thread, one left-hand thread, so rotating the body tightens or loosens both ends simultaneously. That adjustable take-up is the function: it allows a rigging assembly to be lengthened or shortened in place without disconnecting the end fittings from their connection points.

Crosby turnbuckles are forged steel, available in the standard end fitting combinations: hook-and-hook, jaw-and-jaw, eye-and-eye, and mixed configurations. The end fitting selection depends on what the turnbuckle connects to at each end.

Turnbuckles in rigging service fall under ASME B30.26-2015 (Rigging Hardware), which governs design factors, WLL marking, and inspection requirements. Crosby turnbuckle bodies and end fittings carry WLL markings per these requirements.

Types of Crosby Turnbuckles

Hook-and-Hook Turnbuckles

Hook-and-hook turnbuckles connect to links, rings, and hardware at both ends. The hook-end connection is quick, no pin to thread or jaw bolt to tighten. Common in deck rigging, temporary bracing, and field setups where the connections change frequently and latch engagement is acceptable.

Jaw-and-Jaw Turnbuckles

Jaw-and-jaw turnbuckles use clevis jaws on both ends, connecting via a jaw pin and cotter. The jaw connection is a positive pin connection, more secure than a hook for rigging under sustained tension or vibration. Common in structural bracing, offshore standing rigging, and permanent tensioning applications.

Eye-and-Eye Turnbuckles

Eye-and-eye turnbuckles have closed eyes on both ends for shackle connections. The eye-to-shackle connection gives a more secure, documented connection geometry than hooks at both ends. Used in crane back-stays, guy wire assemblies, and rigging where the connection hardware is shackles.

Mixed Configuration Turnbuckles

Mixed configurations, jaw-and-eye, hook-and-jaw, allow one end's connection type to match available hardware without swapping out a complete turnbuckle. Crosby produces these in the standard take-up body sizes.

Crosby Turnbuckle Sizes and Working Load Limits

Crosby turnbuckles cover WLL ranges from light rigging work through heavy structural tensioning applications. Body size and take-up range vary by model, Crosby catalog data is the reference for specific WLL and take-up specifications.

Materials :

• Forged steel body and end fittings.
• Self-colored or hot-dip galvanized depending on model.

Marking :

• WLL and manufacturer identification per ASME B30.26-2015 (Rigging Hardware).

Why Crosby for Turnbuckles

Crosby's forged turnbuckle line carries the same ASME B30.26-2015 (Rigging Hardware) compliance and lot traceability as the rest of their hardware catalog. For applications where turnbuckles need to appear on equipment registers or satisfy third-party inspection documentation, the WLL marking and Crosby manufacturer documentation provide what's needed.

The forged construction on Crosby's end fittings, particularly the jaw-and-jaw bodies used in standing rigging, is what the long-term tension applications require. Cast turnbuckle end fittings are common in lower-duty hardware; forged is the specification for rated rigging service.

Holloway Houston also offers rigging inspection services. Our qualified inspectors examine turnbuckles and rigging hardware per ASME B30.26-2015 (Rigging Hardware) and OSHA standards.

Crosby Turnbuckle Applications by Industry

• Offshore and Marine : Standing rigging, back-stay tensioning, and structural bracing on platforms and vessels where jaw-and-jaw configurations are the standard for sustained tension under vibration.
• Construction Rigging : Temporary bracing on structural steel columns, shoring assemblies, and crane back-stays where tension adjustment is part of the erection sequence.
• Crane and Hoist Work : Back-stay and strut tensioning on mobile cranes and jib cranes where the turnbuckle is part of the rated load path.
• Marine Deck Equipment : Running and standing rigging on ships and barges where corrosion-resistant finishes and positive jaw connections are the specification.
• Utilities and Communications : Guy wire tensioning on transmission towers and communication structures where turnbuckle take-up compensates for seasonal wire movement.

Turnbuckle Safety and Awareness

Turnbuckles in load-handling service fall under ASME B30.26-2015 (Rigging Hardware). OSHA 1926.251 references rigging hardware in jobsite use.

Key awareness points for turnbuckles in service:

• Turnbuckle bodies have both right-hand and left-hand threaded ends. Rotating the body in one direction tightens both ends; the opposite direction loosens both ends. Marking on the body or ends indicates the thread direction.
• When a turnbuckle is fully tightened, at least a full thread engagement on each end should remain visible. Minimal thread engagement at the body end indicates the turnbuckle is near the limit of its take-up range.
• Locking the turnbuckle body prevents accidental rotation during service. Common methods include lock wire, jam nuts, or safety wire, the specific method depends on application requirements.
• Pre-use inspection of turnbuckles covers the body for cracks or deformation, the end fitting threads for damage or wear, and the jaw pins and cotter pins for condition.
