This is an accessory for GRABO suction gripsters. It is not a suction gripster on its own. The 400mm (16in x 16in) SMART CUT seal for the GRABO HIGH FLOW Suction Plate 400, and the answer to big, rough, thirsty pavers. Precision cutting gives the foam channels that hold a seal against deep grooves and open, extremely porous stone. Combined with the larger 400 plate it gives the biggest, most reliable footprint in the HIGH FLOW range, so heavy material stays gripped instead of creeping. Leak-free lifting on surfaces that would defeat a smaller suction gripper, and a straightforward upgrade for anyone whose vacuum gripsters spend their days on hardscape rather than tile. Fits the Suction Plate 400 only. Use the SMART CUT 300 with the 300mm plate. Keep spares: foam is the one consumable on these vacuum lifters. It is the pad that keeps a 400mm gripster honest on split-face stone, and the one most hardscape crews run on the gripper year-round. Product details SKU FS400-SC Brand GRABO Condition New
