How strong should tie down straps be?
Breaking Strength/Working Load Limit Each ratchet-based tie-down strap should have a breaking strength rating, and the working load limit is about 1/3 of breaking strength. A strap that breaks at 1000 pounds is able to safely hold a 300 pound load.
How do you size a ratchet strap?
Example, if you are hauling something that weights 5,000 lbs, you must use the amount of straps that have a total working load of 5,000 lbs or more. If you are using 2” ratchet straps that have a wll of 3,333 lbs, the you should use a minimum of 2 straps.
How much weight do tie down straps hold?
They are designed for use with medium-sized loads such as dirt bikes and ATVs, and can have up to a 500-lb working load and 1,500-lb breaking strength. They are easy and quicker to tighten and release than a ratchet strap, but cannot safely secure as much weight.

How do you calculate work load?
The WLL is calculated by dividing MBL by a safety factor (SF). An example of this would be a chain that has a MBL of 2000 lbf (8.89 kN) would have a SWL or WLL of 400 lbf (1.78 kN) if a safety factor of 5 (5:1, 5 to 1, or 1/5) is used.
How do you calculate breaking strength?
The basic breaking strength factor for manila line is found by multiplying the square of the circumference of the line by 900 lbs. When you purchase line you will buy it by its diameter. However, for purposes of the USCG license exams, all lines must be measured by circumference. To convert use the following formula.
