It was a 2" single ply lifting strap. So the 3200 lb capacity is the safe load limit.
It was not a cheap tow strap but one designed for lifting overhead with a crane or the like.
I'm not sure what the rated break strength is, I'll have to try and find out.
Probably 3x -- or 10,000 pounds.
Sportsmans Guide recently sent me a specials catalog with surplus military 4" straps. Check 'em out. Although I have used my 2"/20,000 pound strap to unstick a tour bus, the FedEx delivery truck, and the UPS delivery truck. But I drive a Cherokee with a standard 2" hitch. So far I haven't mangled it, and I'd prefer not to start now.
