4" Blackline Heavy Duty Cargo Strap with Chain Extension

These 4" Blackline heavy-duty cargo straps are built to handle the toughest securement jobs. Constructed from industrial-strength polyester webbing with a break strength of 24,000 lbs. and a working load limit of 6,670 lbs., they are 23.5% stronger than standard 4" straps. The webbing is designed with superior abrasion resistance, featuring a thicker edge made from concentrated webbing to slow down wear (though edge protection is still recommended).

The 30-foot strap fits standard 4" winches.

Why Choose 3/8" Chain Extension End Hardware?

Chain extensions combine the strength of Grade 70 transport chain with the flexibility of polyester webbing. This allows you to use rub rails or stake pockets without damaging the webbing. The extra-long 34" chain extension is easier to wrap around stake pockets and provides a stronger, more secure hold. Each extension includes a 3" D-ring, a 30" chain, and a clevis grab hook for quick, reliable connections. Zinc plating on the chain extension adds protection from the elements and ensures long-lasting performance.

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.

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."
