Use Guide
How To Use And Inspect 4" Winch Strap with Chain Extension
- Match the stamped working load limit to the calculated load, not the winch capacity
- Inspect the chain, hook, and stitching before each use for wear or damage
- Ensure the webbing runs freely through the grab hook without twisting
- Avoid sharp edges or abrasive surfaces that can cut the webbing
- Do not exceed the 7,300 lb working load under dynamic conditions
