4″ x 30′ Blackline Heavy Duty Tie Down Strap with Chain Extension
Our 4″ wide heavy-duty ratchet 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 end fittings and the ratchet assembly have a zinc plating for protection from the elements.
Compliant with Industry Standards
This 4 inch ratchet 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 extensions are 18″ long with a 4″ D-ring and clevis grab hook for quick and secure connections.

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.”
What is Design Factor?
According to 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.
