X-Grip
for 3-4 in. phones, 1.5 in. ball (size C),
The principle of the X-Grip holders is as easy as pie. A phone or tablet is placed between the ends of two rubberized-intersecting arms, which are then drawn together by a spring. The result: a secure mounting for your device. The larger X-Grip holders for tablets from 10 inches get additional support by other arms.
