Rigid Handles put a handle where you want it on awkward, bulky items, such as storm windows, office furniture and appliances. The TL6RH is designed for gripping curved surfaces, the LP6RH for flat surfaces.
Unlike suction cups that produce a vacuum when they are pulled away from the surface, Powr-Grip vacuum cups pump out air from between the rubber pad and the surface, thus creating a much more reliable hold. The hand-actuated pump is spring-balanced to
provide a vacuum of 20 inches Hg (at sea level).
A red line on the plunger indicates the vacuum level of the hand cup. When the cup is attached completely, the plunger is partially hidden inside the pump and the red line is not visible. A visible red line indicates vacuum is not sufficient for a lift.
If the red line starts to show during a lift, a check valve allows the operator to repump the cup without losing the remaining vacuum. When the lift is completed, a release device allows air to refill the evacuated space, so that release is complete,
with no dangerous after-stick. |
