CRL Pump-Up Vacuum Lifters are designed to make the carrying and lifting of large glass sheets, marble or stone safe and easy. The handle is composed of tough ABS plastic, and the rubber suction cup has a diameter of 10" (254 mm). Vacuum attachment to flat, non-porous surfaces is achieved in a few seconds by depressing the pump's plunger until it stays well within the handle, beyond the red-line safety indicator. 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 the delicate surface, and is released instantly from the material by pressing the thumb release. It comes with a protective carrying case.
