*Q: What is the strength rating I need?
*A: A strap's overall strength is limited by its weakest point. This can be the webbing or it can be the buckle. You need to understand that there are "breaking" strengths and there are "working loads". The breaking strength is where the webbing or the buckle will actually fail under a static load (a dead lift, for instance). On the other hand, working loads are a recommended maximum load to use considering other factors like impacts, shocks to the strap from dropping or jarring, etc. Most manufacturers recommend 33-50% of the breaking strength as the actual working load (we figure at 50%). If your buckle is rated at 1000 lbs, and your webbing is rated at 500 lbs, you have to figure your working load as 50% of the webbing's rating, or 250 lbs. Our cam strap webbings are rated as follows...Lightweight Polypropylene-600 lbs; Heavyweight Polypropylene-900 lbs; Flat Nylon Webbing-3500 lbs; and Polyester-3500 lbs.
