4" x 40' Green Heavy Duty Cargo Strap with Chain Extension

Trailer winch straps are one of the most common pieces of tie down equipment for flatbeds and other trailers. Used in combination with winches and other related hardware, their versatility makes them the ideal choice for a wide range of cargo.

The rugged polyester webbing offers very little stretch and is abrasion-, UV-, and water-resistant.

HD Truck Strap Features

The yarn used to make our webbing is slightly thicker than that offered by most competitors, with more picks per inch used to create each strap. It's also heat-sealed on the end. Together, these features provide better resistance to abrasion, tearing, and cutting, so your winch straps will last longer.

The 40-foot length strap fits standard 4" winches.

Compliant with Industry Standards

All of our trailer winch straps are tested in the USA to ensure they meet all standards - they are tagged and stenciled with the working load limit to meet FMCSA and DOT regulations, CVSA and WSTDA guidelines, and North American Cargo Securement standards.

Learn more about proper load handling and securement in the WSTDA safety bulletins.

Why Choose 3/8" Chain Extension End Hardware?

Chain extensions allow you to combine the strength of grade 70 transport chain with the softness of polyester webbing. You can use the rub rails or stake pockets on your truck or trailer to tie down your cargo without risking damage to the webbing part of the strap. The extensions are 18" long with a 4" D-ring and clevis grab hook for quick and secure connections.

Winch Use Guidelines

According to the WSTDA (section 4.6.8): "When using web tie downs with a winch or ratchet, a minimum of 2 and a maximum of 4 wraps of webbing shall be wound on the winch or ratchet mandrel. Excessive wraps of webbing on the mandrel may reduce the working load limit (WLL) of the web tie down and may interfere with proper operation."

What is Design Factor?

Another term defined by the WSTDA, design factor is the "ratio of the breaking strength to the working load limit" and should be 3:1 for these tie down straps. This builds in a level of redundancy to account for unknown factors, keeping you, your crew, and those around you safe.
