Safety is very important when it comes to transporting your load from one place to another. According to the FMCSA all tie-downs must be attached and secured so that it does not become loose or unfastened, open, or release during transit. The location of these tie-downs must be located inboard of the rub rails. The FMCSA also requires one tie-down to secure a load that is five feet or less in length and weighs 1,100 pounds or less.
