Toolocity ASVC8858B1  8-Inch Adt Vacuum Suction Cup with Lexan Handle for Granite/Glass
8" ADT Vacuum Suction Cup with Lexan Handle for Granite/Glass. Vacuum suction cups are used to lift Nonporous materials such as glass, metal, Formica, plastics, fiberglass, linoleum and polished stones. Surfaces should be free of oil, grease or water, otherwise slipping can occur. The grip these suction cups obtain on a load surface is amazingly strong and has to be experienced to be appreciated.
