Some flatbed and trailer setups don't have a webbing-friendly rail, just rub rails or stake pockets that would chew up soft webbing in a hurry, which is exactly the gap this heavy duty 4" x 40' winch strap with chain extension is built to close. Pair it with a standard 4" mandrel winch, and the chain end lets you hook directly onto rough steel without putting the strap's own webbing anywhere near an edge that could cut it.

The webbing half of the strap is the same heavy-duty polyester used throughout our winch strap lineup, with thicker yarn, more picks per inch, heat-sealed ends, and resistance to UV, water, and abrasion. The 18-inch chain extension itself is grade 70 transport chain, terminating in a 4" D-ring and a clevis grab hook, so you get the toughness of chain where you need it and the softness of webbing everywhere else.

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.
