This is an accessory for GRABO suction gripsters. It is not a suction gripster on its own. The Foam-Rubber Seal Type A1 is the reason a GRABO grips material other suction cups will not touch. This patented, high-friction, closed-cell rubber gasket conforms to heavily textured surfaces and holds a tight vacuum where a rigid cup would simply leak. It fits every GRABO model, keeps dust and debris out of the tool, and is what turns a standard suction gripper into a lifter that works on real jobsite materials rather than polished showroom samples. Your gripster shipped with one already installed. These are replacements, and a seal is a wear part: nick it on a slab edge or wear it thin on abrasive stone and the whole tool underperforms. Keep a spare with the vacuum lifters in your kit and a damaged gasket costs you a minute instead of a day. No other single part changes what these vacuum gripsters and lifters can pick up.
