Just as it’s important to note the breaking strength limit on a strap, you should also be mindful of the limits of your attachment hardware. Shackles also have a stamped load limit on them that applies to lifting and rigging. For our purposes, a 3/4-inch D-shackle will meet our tow and recovery needs. In any case, the shackle used should always be stronger than the strap. Should the shackle break in use, it can quickly become an airborne missile.
