Velbon The Hide Clamp II is the perfect solution for securely mounting your camera, scope, or even some binoculars on a shelf or bar. The G-Clamp mount is ideal for use in bird watching skins and allows stable support in often confined spaces where using a tripod is impossible or practical. As long as the center column of your tripod is removable (and has a diameter of 21 to 28 mm), you can mount and secure it at a comfortable height to keep your gear stable. The Velbon Hide Clamp II includes 4 sleeves of different diameters to accommodate virtually any tripod center column.
