Load Limits and Ratings
WORKING LOAD LIMIT
The maximum cargo weight a tie down strap can safely handle and still accommodate unexpected forces caused by speed, road conditions or emergencies. The industry standard for Working Load Limit is 1/3 of the Assembly Break Strength.
The strength of each component of an assembly. For example, on a 2” Ratchet Strap with Flat Hooks, the ratchet strength is 11,000 lbs, the flat hook strength is 10,000 lbs, and the webbing strength is 12,000 lbs.
The Federal D.O.T. and Web Sling Association require tie down manufacturers to attach a tag to the strap with the safe Working Load Limit.
