How Does Chain Working Load Limit Relate to Break Strength Rating
Question:
Hello, I need to replace the Clevis slip hooks on the end of my trailer safety chains. The chains have a breaking strength of 11,700 pounds and my trailer gross weight rating is 10,000 pounds. I am confused by the working load limit ratings of the Clevis slip hooks and how that relates to trailer weight. I have attached a picture of my current slip hooks. Thank you.

Expert Reply:
A safety chain's working load limit (WLL) is always 1/3 of the chain's break strength and it is the limit you want to stay within in normal use. If your chains have a rated break strength of 11,700-lbs then the correct clevis slip hook you can use is # TCSLIP-G70-8-L which has a WLL of 4700-lbs. This hook fits chains links that are 5/16-inch like your existing hook.
