If you strap down loads for a living, these tools do the math for you. They follow the federal securement rules in 49 CFR 393, the same ones a roadside inspector checks against, so you can be sure a load is legal before you pull away.

Most used
Working load limits (6)
Every strap, chain and net has a safe working limit, and it is far lower than the breaking strength printed on the label. These tools tell you what your hardware can actually hold and how many pieces you need for the weight you are carrying.
Flatbed loads (6)
Lumber, steel coils and machinery each have their own tie-down rules. Pick the load you are hauling and get the exact number of straps and where they belong.
Inspections & compliance (9)
Check your straps for damage, run a proper pre-trip walkaround, and test yourself on the FMCSA rules before an inspector does it for you.
Pickup & moving (2)
Not a commercial driver? These cover the everyday jobs: holding a load steady in a pickup bed, and stopping furniture from shifting in a rental truck.
