Superior brand Poly Load Protectors fit on your forklift's forks like fork extensions or a slipper to give a 1/4" of urethane coating to the forks. This creates a non-slip surface between your load and the steel of the forks eliminating costly damage from lift truck handling. The heel is reinforced with an implanted fiberglas mesh to resist tear out. The 91 shore A polyurethane has has just enough cushion to allow the load to slightly compress, but is hard enough to resist cutting.
