One end is sewn with a loop for the header bracket the other end is laced in the blower restraint plate and once length is figured out simply fold over extra strap out of the way or trim off.
Straps are sold in sets of four. Restraint straps are currently out of cert. and are perfect for a hot rod or could be run in a class where SFI certification is not needed. Aluminized covering is flaking and gives the straps a nice patina if you are going after that seasoned look on your hot rod.
