The Sink Hole Saver™ Manual is a surface-mounted reinforcement system that strengthens fragile materials during lifting, transportation, and installation. This product features proprietary, non-marking vacuum cups with triple sealing rings for a strong, reliable hold—even on textured and leathered surfaces. Vacuum cups can be re-pumped in place without loss of remaining suction, and red-collar indicators on thumb pumps allow vacuum pressure to be monitored at a glance. New knurled lock-knobs allow quick repositioning of cups around cutouts. The Sink Hole Saver™ Manual is available in three lengths, with three optional accessories (Angle Bracket, Vertical Lifting Handle Kit, and Extension Bracket Kit), to provide a protection solution for any situation.
