<p>The vacuum suction cup has a handle to lift and carry objects with flat and smooth surfaces. It is useful to install glazed tiles or glass panels or similar objects. The suction cup is attached to the surface by pressing it down until the air has escaped. To make it quick and effortless to separate the suction cup from the surface, the handle is provided with an integral relief valve. This allows the vacuum to be broken without applying any force to the suction cup.</p> |
