Rigging Hardware Turnbuckles for Precision Adjustment
A turnbuckle is a mechanical device used to adjust the length or tension of ropes, cables, and tie rods without disconnecting the system. Its design features a central body with right-hand and left-hand threaded ends, allowing precise adjustment by rotating the frame.
Turnbuckles are essential rigging hardware in lifting, bracing, suspension, and anchoring systems where secure and accurate tension control is required.

Types of Turnbuckles
The performance of a turnbuckle depends on the type of end fittings and the application requirements. Holloway Houston supplies multiple configurations to meet different rigging challenges
Eye & Eye Turnbuckles
Both ends terminate in eye fittings. Used for connecting shackles, hooks, or wire rope in tensioning and alignment systems. Preferred in applications requiring inline adjustment without disconnecting the load path.
Hook & Hook Turnbuckles
Open hook ends on both terminals. Allows rapid connection and adjustment in temporary rigging setups. Best suited for non-permanent installations where frequent reconfiguration is required.
Jaw & Jaw Turnbuckles
Clevis jaw terminals secured with removable pins. Provides rigid connection to anchor points, structural fittings, or rod assemblies. Preferred for high-load anchoring and tie-rod applications.
Eye & Jaw Turnbuckles
One eye terminal, one clevis jaw terminal. Combines inline connection capability with rigid anchoring. Used where one end requires a shackle or hook, and the other attaches to a fixed structure.
Turnbuckle Jaw Ends
Replacement jaw fittings for field assembly or repair. Allows reconfiguration of existing assemblies without replacing the complete turnbuckle body.
Turnbuckle Locknuts
Locknuts prevent rotation under load or vibration. Used to maintain tension setting and prevent inadvertent adjustment during operation.
Turnbuckle Bodies
Center frame with internal right-hand and left-hand threads. Accepts various end fittings and provides rotational adjustment for tension control and length variation.
Turnbuckle Eye Ends
Eye terminals for connection to shackles, hooks, or wire rope. Used in field-assembled turnbuckle configurations requiring inline attachment points.
Turnbuckle Categories by Size and Capacity
Holloway Houston provides turnbuckles in multiple sizes and load capacities, offering flexible options for lifting, rigging, tensioning, and structural applications.
Take-Up Lengths
Offered in 6", 9", 12", 18", and 24" lengths, giving flexibility for short-range adjustments or longer stretches in lifting, rigging, and tensioning applications.
Working Load Limits(WLL)
Options range from light-duty applications to heavy-duty assemblies rated over 30 tons, designed to manage everyday lifting applications and major industrial lifting challenges.

Turnbuckle Selection Guide
Choosing the right turnbuckle is important to make sure your lifting or rigging work is safe and effective. Start by looking at the working load limit (WLL) and pick a turnbuckle that can handle more than the load you plan to lift. Consider the type of end fittings: eye fittings connect to hooks or shackles, hook fittings allow quick attachment, and jaw fittings provide a strong connection to anchors or rods. Also, check the thread type and the adjustment length to make sure it fits your setup.
The material of the turnbuckle matters too. Galvanized steel works well for normal indoor or outdoor use, while stainless steel is better for marine or chemical environments where corrosion is a concern. Always match the turnbuckle size to the hardware it will connect to, not just the rope, cable, or rod. A proper choice will make your work safer and smoother.
Turnbuckle Safety Tips / Best Practices
- Inspect before use: Check for cracks, wear, or corrosion before each use.
- Do not overload: Never exceed the working load limit.
- Avoid side pressure: Use only for straight-line tension, not sideways force.
- Secure properly: Use locknuts or safety pins to prevent loosening under vibration or heavy loads.
- Lubricate threads: Apply light lubrication to make adjustments easier and reduce wear.
- Replace when damaged: Immediately replace any damaged or worn turnbuckles.
- Regular inspection: Consistent checks and proper handling extend lifespan and ensure safety.
