4" x 30' Blackline Heavy Duty Tie Down Strap with Chain Extension

These 4" Blackline heavy-duty ratchet straps are built to deliver maximum strength and durability. Made from industrial-strength polyester webbing with a break strength of 24,000 lbs. and a working load limit of 6,670 lbs., they’re 23.5% stronger than standard 4" straps.

The webbing is engineered for superior abrasion resistance, with a reinforced edge made from concentrated webbing that slows down wear (though edge protection is still recommended).

Both the ratchet assembly and chain extension are zinc-plated for added durability and corrosion resistance.

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 secure loads using rub rails or stake pockets without risking damage to the webbing. Each 18" extension includes a 4" D-ring and a clevis grab hook for quick, reliable connections, making it easier to secure heavy-duty loads with confidence.

All of US Cargo Control's ratchet straps 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.

Ratchet 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."
