Fits all 1 1/2" webbing. The stainless steel triangular tensioner holds the webbing tight, deters tearing from impact and allows easy re-tightening if the webbing becomes loose due to impact or stretching from snow and ice load. The tensioners swivel back and forth and rotate around the plastic insulated post bracket allowing for up and down grade changes which prevents the tape from bunching in the tensioner. 2 per package.
