PadSAVERS increase the life of screen vac hook face pads. The PadSAVER is an interface that attaches between the pad and the abrasive. Over time hook material on the face of the pad wears out and no longer can deliver adequate holding force for the abrasive. With PadSAVERS the hook material on the PadSAVERS wears out and not the pad. Simply replace the PadSAVERS at a fraction of the cost.
