Jaw & Jaw Turnbuckles

Jaw-Jaw Turnbuckles

Adjustable Tensioning for Pinned Connections

Jaw-jaw turnbuckles are used to create adjustable tension between two fixed connection points, typically in assemblies where bolts or pins are already in place. With a clevis (U-shaped) jaw and removable pin on both ends, these turnbuckles make it easy to connect to components such as lifting lugs, anchor plates, or other rigging hardware. This makes them a strong choice for structural, industrial, and rigging applications that demand a firm and stable link between tensioned lines.

Unlike open hooks or closed eyes, jaw ends can be pinned directly to an attachment, which reduces slippage and movement under load. This is especially useful when handling equipment, supporting framework, or securing cables that must remain in fixed alignment.

Sizes and Load Capacities

Holloway Houston stocks jaw-jaw turnbuckles in a variety of sizes to suit different tensioning needs. These units are available in thread diameters ranging from 1/2" up to 1-1/4", with adjustable take-up lengths between 6" and 18", depending on the model. This flexibility allows users to fine-tune tension across different spans.

The working load limits (WLL) start at 2,200 lbs and go up to 13,860 lbs, offering compatibility with everything from lightweight tensioning tasks to more demanding setups in construction or heavy rigging.

All units are made from steel and typically finished in galvanized coating for corrosion protection. This makes them fit for both indoor and outdoor use.

Where Jaw-Jaw Turnbuckles Work Best

These turnbuckles are commonly used in:

• Structural bracing and support systems
• Marine and rigging assemblies requiring pinned connections
• Lifting assemblies where rotation or slippage must be prevented
• Guy wire and suspension setups in construction and utilities
• Theatrical rigging grids and safety cable installations

Because of the clevis design, jaw-jaw types are often chosen when the tensioned element connects to equipment or hardware that already has a mounting hole or tab.

Benefits of Jaw-Jaw Turnbuckles

• Fixed, secure connection using clevis pins
• No hook movement under tension
• Rotating frame allows mid-line length adjustment
• Galvanized finish resists weathering
• Available in multiple lengths and load capacities

Helpful Tips for Choosing the Right One

When selecting a jaw-jaw turnbuckle:

• Measure your needed take-up distance – 6" may be enough for minor adjustments, but 12"–18" gives better range for structural systems.
• Match WLL with load expectations – Always select a turnbuckle rated higher than your expected load.
• Check your anchor point – The jaws work best with flat plates or tabs with a drilled hole to insert the pin.
• Inspect before use – Make sure pins are properly secured and that no threads are damaged.
• Avoid vibration-heavy systems unless safety pins or lock nuts are used.

Related Hardware and Alternatives

If a jaw-jaw configuration doesn’t match your rigging setup, you may want to explore:

• Eye-Jaw Turnbuckles – Combine a fixed loop on one side and a clevis on the other
• Eye-Eye Turnbuckles – Used for more permanent installations
• Hooks & Swivels – Useful for motion or dynamic loads
• Lifting Shackles – Often used with jaw ends for secure load paths
• Wire Rope Accessories – Complete your cable or tensioned system

These alternatives can be filtered based on WLL, end type, and usage.

Practical Use Cases

In job sites, jaw-jaw turnbuckles are often found in bracing systems for towers, lifting frames, scaffold supports, and suspended fixtures. The clevis pins make it easy to swap out components or re-tension without disconnecting entire lines. They also play a role in lifting systems that cannot rotate or twist under load, making them compatible with shackles and load cells.

For users working in temporary structures or needing fast-release tools, hook-hook versions may be preferred. But for anything requiring secure tension, jaw-jaw remains one of the most reliable configurations for static, heavy, or safety-critical assemblies.

Final Overview

Jaw-jaw turnbuckles provide solid, pin-to-pin tensioning for fixed systems. Their double-clevis design eliminates the slack or swing you might see in hook configurations and gives you a strong, dependable hold between two hardware points. At Holloway Houston, you'll find them in multiple sizes, lengths, and WLLs, ready to support your field or shop-based projects.

Each listing includes specs, material details, and size filters so you can pick exactly what fits your need—whether it's a short-term cable brace or a permanent lifting structure.
