QEP's ProMAXGrip Double Suction Cup is ideal to lift, position and set large format tile. Its dual action, suction and release system has a holding power of 175 lbs. when used on clean, smooth, non-porous surfaces, and can be used on vertical and horizontal applications. To use, simply squeeze bar under handle to engage suction and push button on top forward to release suction. Featuring large suction pads that will not mar tile, this double suction cup is designed with a wide base for better balance, and a rigid, textured, non-slip grip for easy, single hand operation. For best results, wipe the tile surface clean before applying, and ensure the suction cup underside is clean and dust-free.
