Description

4" x 37' Blackline Heavy Duty Cargo Strap with Chain Extension

Our 4" wide heavy-duty winch straps are made to last. Constructed from industrial-strength webbing with a break strength of 24,000 lbs., they have a working load limit of 6,670 lbs., 23.5% higher than our standard 4" straps! The webbing also offers superior abrasion-resistance, part of which comes from a thicker edge made from concentrated webbing. This slows down the abrasion-process (but doesn't prevent it, so you'll still need edge protection). The chain extension has a zinc plating for protection from the elements.

The 37-foot length strap fits standard 4" winches.

Compliant with Industry Standards

This 4 inch winch strap is tagged with the working load limit to meet CVSA guidelines, FMCSA and DOT regulations, and WSTDA, CHP 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 extra-length 34" chain extension is also easier to wrap around your stake pocket. This is best practice and not only provides a better, more secure hold but also gives you the full working load limit of the stake pocket. It has a 3" D-ring, a 30" chain, and a clevis grab hook for quick and secure connections.

Custom Winch Straps Available

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.
