CRL Pump-Up Vacuum Lifters are designed to make the carrying and lifting of large glass sheets, marble, and stone, safe and easy. The handle is composed of tough ABS plastic that is attached to a precision molded rubber suction pad. The four extra mounting points set these Lifters apart from other pump style vacuum lifters. Vacuum attachment to flat, non-porous surfaces is achieved in a few seconds by depressing the pump's plunger five or six times until it stays well within the handle, beyond the red safety band, which is easily seen against the light gray plunger color. Once attachment has been achieved the glass sheet can be lifted easily by hand. The rubber cup has the capability of handling almost any manual lift without damaging any delicate surface, and is released instantly from the material by pressing the thumb release. The heavy 3/16" (5 mm) walls of the handle resist bending and will not dent like metal handles. The S108 has an 8" (203 mm) diameter rubber vacuum pad and lifting capacity of 125 pounds (56 kg). Comes with protective carrying case .
