Made with both professionals and hobbyists in mind, the T28379 Vacuum Clamp Set is suited for edge-banding or edge tape application on large work pieces, including doors, panels, and countertops. Simply adhere the vacuum or C-clamp to stabilizing surface and workpiece, and flip the fasteners. Each vacuum cup can hold up to 75 lbs. of pressure, and since the cups are made of rubber, there will be no need to worry about potential damage to the workpiece or stabilizing surface. Each set comes with two vacuum clamps and an interlockable case.
