Tether Tools Rock Solid PowrGrip 3"

The Tether Tools Rock Solid PowrGrip 3" securely mounts your iPhone or smartphone almost anywhere. The secure and versatile vacuum mounting system includes a ballhead assembly to optimally position and angle the phone or device. The ballhead assembly is compatible with any 1/4"-20 mounting bracket. 

The vacuum PowrGrip attaches and releases in seconds and can be moved quickly from one place to another on windows, mirrors, autos, RVs, boats, counter-tops, or any smooth, non-porous surface. The Ballhead Assembly enables easy angle positioning and, in addition to smartphones and devices, can also mount other small accessories such as a point and shoot or video cameras up to 6lbs (2.7kg).

Unlike a suction cup mount that is pressed onto a surface and then creates a seal by pulling away from the surface, PowrGrip vacuum cups use a hand-actuated pump to efficiently remove air from between the rubber pad and the attaching surface, creating a much more reliable, longer lasting hold. This is the same mounting technology used on commercial film or photo shoots and the same solutions employed for industrial uses such as transporting large pieces of glass and mirrors. Because the full face of the pad is brought into contact with the surface, distortion is reduced, allowing the cup to be used on materials of almost any thickness with minimal risk of damage. The rubber pad won’t mar or damage most surfaces.

A spring-balanced pump ensures a consistent vacuum level and the red-line indicator warns if there is any drop in holding power. Just a few pumps of the plunger will remove the air from between the mount’s vacuum pad and the mounting surface. As long as the mount maintains a reliable hold, the plunger remains partially hidden inside the pump and the red line is not visible. If the red line appears, another pump or two will restore full holding power. To release the vacuum cup, push on the rubber tabs at the edge of the pad and the mount will release from the attached surface.
