The RMAMPS1420 4-Hole AMPS Mounting Pedestal is part of Arkon’s Robust Mount Series and is compatible with all cameras with the standard 1/4”-20 camera pattern, including those from Nikon, Sony, Samsung, Canon, Fujifilm, Olympus, Panasonic, and Pentax. It can be drilled into solid, flat surfaces, such as walls, tables, and workbenches using the 4-Hole AMPS pattern. The AMPS pattern consists of four holes located in a rectangular pattern spaced at 30.17mm x 38.05mm (measured as the center-to-center distance between holes). This package includes only the Heavy-Duty 4-Hole AMPS mounting pedestal with 1/4”-20 mounting bolt head. This tough, low-vibration pedestal measures approximately 4.5 inches high from the bottom of the AMPS base to the top of the pedestal (not including the holder), and is made of a combination of plastic and glass fiber. To install the camera, simply screw the camera’s 1/4”-20 mounting pattern onto the mount’s 1/4”-20 mounting bolt and position the mount and camera as needed by loosening or tightening the side adjustment knob. The arm of the pedestal swivels on both the top and the bottom, providing 360-degree rotation and the ultimate flexibility in positioning the camera at any angle.
