INSTRUCTIONS & CAUTIONS
Proper Installation
When installing the jaw eye turnbuckle, make sure both the jaw and eye fittings are securely attached to their anchor points. Use the right-sized pins (clevis or bolt pins) to ensure a tight and safe connection. Be sure to tighten the turnbuckle body fully to remove any slack before adding tension. This helps your rigging system stay secure and functional.
Regular Inspection
Always inspect the turnbuckle before each use. Look closely for signs of wear, rust, or damage on the jaw, eye, and threads. If you find any issues, replace the turnbuckle right away. Regular checks are key to keeping your rigging gear working properly and preventing unexpected failures.
Avoid Over-Tightening
Don’t over-tighten the turnbuckle. Doing so can stress the components, damaging the threads or causing failure under load. Stick to the manufacturer’s recommended torque specifications to keep everything running smoothly and avoid damaging the equipment.
Correct Load Handling
Always make sure the load you’re handling is within the specified capacity for the turnbuckle. Exceeding the working load limit can cause premature wear or even failure. Double-check the load limits before each use to ensure you’re operating safely.
