Working Load Limit vs Breaking Strength for Ratchet Straps SHK563MR

Hi CJ, Great question! The working load limit and breaking strength tell you two different things about how much a strap can handle.

The working load limit is the maximum load the strap is rated to safely secure during normal use, while the breaking strength is the force at which the strap is expected to fail under testing. For the Shocker Hitch Retractable Ratchet Straps, part # SHK563MR, each 2" wide x 10' long strap has a working load limit of 1,467 lbs and a breaking strength of 4,400 lbs.

I like to emphasize the working load limit when securing cargo because that's the rating you want to use when determining whether the straps are suitable for your load. The breaking strength is not the amount you should plan to put on the strap during use. Since this kit includes four straps, you'll also want to make sure the total securement capacity is appropriate for your cargo and how it's tied down.

What are you planning to secure with these straps?
