The Grab-It! Universal Mount attaches to almost any smooth surface and grips almost any device with a few simple pumps of its state-of-the-art ForceLock Valves. Using airlock technology similar to that found on submarines and spacecraft the pumping creates negative pressure between the suction cup ends and the contact surfaces. The air is forced out resulting in a strong vacuum that holds without clamps clips or sticky pads. To detach simply press the valve and the suction lock is released for easy removal. Plastics. Black.
