The RMVESAMPS drill-base mounting pedestal is part of Arkon's Robust Mount Series. It can replace or upgrade an existing pedestal and mounts to walls or other solid flat surfaces with screws using the 4-Hole AMPS mounting pattern. The pedestal is compatible with devices having a VESA 75 or VESA 100 mounting pattern. This mount includes only the Heavy-Duty 4-Hole AMPS Mounting Pedestal with a VESA 75/VESA 100 Compatible Head. Holders and devices sold separately. 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 tough, low-vibration pedestal measures 4.5 inches high from the bottom of the mount base to the top of the mount pedestal (not including holder), and is made of a combination of plastic and glass fiber. The arm of the pedestal swivels on both the top and the bottom, providing 360-degree rotation and the ultimate flexibility in positioning the VESA-compatible device at any angle.
