Our Plastic Single Pad Vacuum Lifter is easy-to-attach with its split-handle design for one-hand operation. It is lightweight yet tough, and its 4-1/2" (114 mm) diameter rubber pad lifts up to 66 lbs. (30 kg) when applied to smooth, non-porous surfaces. Place it firmly against the glass; flip up the handle actuator and lift. It's that quick and easy!
