All Kinedyne® ratchet straps are rated as a whole assembly (not the individual components) and are Tagged and Stenciled in accordance to North American Regulations: Manufacturers Name, Working Load Limit in Pounds and Kilograms.
The Difference between Breaking Strength and Working Load Limit is: Breaking Strength refers to the point in which the tie-down you are using is going to fail. Working Load Limit is the maximum allowable load assigned to each tie down by the manufacturer which does not to exceed one-third of the complete assembly breaking strength.
WARNING: Series E, A or F fittings are designed for use with Kinedyne Logistic Track. Load ratings may be reduced when used with other tracks or if the track fitting is not positively engaged. Your cargo control system is only as strong as its weakest link. All ratings for series E and A fittings are based on use with Kinedyne 11 gauge track. NOTE: Several types of Kinedyne track are not made with 11 gauge steel, contact Customer Service for specifications by part number.
