RATCHET STRAP CALCULATOR — HOW MANY YOUR LOAD NEEDS
Guessing costs you either a fine or a damaged load. Enter cargo weight and your strap working load limit for the number of ratchet straps required to meet the federal 50 percent aggregate rule.
Ratchet Strap Load Calculator — Get the Right WLL for Your Cargo
Not all ratchet straps are rated the same. The WLL you need depends on your load weight, not the tag colour.
Enter cargo weight and quantity of straps. The calculator returns the minimum WLL per strap and checks your setup against FMCSA §393.106.
Under-rated ratchet straps snap under dynamic loading — not static load. FMCSA violation for insufficient WLL requires only that your straps can’t handle the load.
Drivers, loaders, and freight teams using ratchet straps on any vehicle.
- FMCSA 49 CFR §393.106
