This 4 inch by 50 foot winch strap contains a heavy duty flat hook that attaches to a flatbed trailer. The winch strap is made of industrial grade, 20,000 lb polyester webbing and will securely tie down your load with any standard 4" winch. Winch bars and truck winches are used to make this a complete flatbed tie down system. To help prevent the winch strap from wearing out at the point of contact with the flat hook, the hook contains a round piece of metal on the inside of the opening known as a defender. By having a defender at this point of contact, the life of the strap is prolonged.
