Break Strength and Working Load Limit:
In learning how to use ratchet tie down straps, it’s important to use a strap based on the Break Strength (BS) and working load limit (WLL).
Each component of a ratchet strap assembly- the webbing, the ratchet, and the end fittings- have a break strength that is determined through independent testing. The break strength is the amount of weight a component can withstand before failing.
Because a tie down assembly is only as strong as its weakest point, the component with the lowest break strength is considered the break strength of the entire ratchet strap assembly.
The working load limit is then determined based on the break strength. The working load limit is figured by taking 1/3 of the break strength of the weakest component. This means a tie down strap with an assembly break strength of 10,000 lbs. would have a working load limit of 3,333 lbs. An assembly should never be used in applications over its working load limit.
All of our ratchet straps are manufactured with labels attached that include break strength and work load limit information.
They also meet several requirements, including:
Custom Ratchet Straps
Custom ratchet straps are always an option at US Cargo Control. Because we sew and assemble all of our ratchet straps on site in our Iowa facility, a custom strap is cost-efficient and shipped quickly. There are no minimum quantities required to order a custom ratchet strap.

Ratchet Straps vs. Cam Straps
The terms ratchet straps and cam straps are sometimes used interchangeably since they’re both used to tie down cargo with polyester webbing. There are some key differences between ratchet straps and cam straps and you should choose based on what you are hauling. This video outlines the difference between ratchet straps and cam straps:
