Factor 55 tow straps are manufactured in the USA from a low stretch 100% Polyester material. We prefer the versatility of a narrower 2 inch strap versus wider 3 and 4 inch straps. 2 inch straps can easily fit into common ? screw pin shackle openings and we have discovered that the edges of 2 inch straps do not get abraded as easily as wider 3 and 4 inch wide straps. To reach a higher minimum breaking strength of 31,000 pounds (USA Tested and repeatable), we doubled the ply and stitched it the entire length and wrapped the reinforced eyes with a durable Cordura sleeve. Because of its low stretch quality, these straps can also be used as a 30 foot winch extension. Each Factor 55 Tow Strap is individually serialized for material lot traceability as well as properly labeled for different load configurations.
