This 4" Roll Off Container Winch Strap from US Cargo Control offers superior security to any roll off box. Each winch strap measures 5' (60") in length for the optimal amount of webbing for roll-off containers which require less excess webbing, and measures 4" wide to fit into any standard winch for adjustment. These cargo straps are made of durable polyester webbing that can tie down working loads of up to 5,000 lbs. and have a breaking strength of 20,000 lbs. Our 4 inch straps are fitted with extra large flat hooks that fasten easily to the roll off container and sewn loop ends to loop onto any existing trailer hooks. The trailer winch strap meets the necessary safety compliance requirements set by the Department of Transportation (DOT) and Web Sling & Tie Down Association (WSTDA) and comes with working load limit tags for security. Roll-off container straps must be used to secure these containers before transport according to the DOT. Add this Roll Off Container Winch Strap from US Cargo Control to your existing winch accessories and make the cargo tie down process much safer and easier.
