Arkon's CMPHD003 Heavy-Duty Aluminum Drill-Base Mount with 22'' Adjustable Arm is designed for installations where mounting a camera to a wall or other surface (including car floors) is desired. This mount includes Arkon's Heavy-Duty Aluminum Mount with 22'' Arm and 4-Hole AMPS Drill Base. The mount base uses a 4-Hole AMPS pattern to attach to the wall (screws are included) or other surface. (Formerly an industry standard, the 4-Hole AMPS pattern consists of four holes located in a rectangular pattern spaced at 1.188" by 1.813''.) The CMPHD003 offers a 1/4''-20 mounting bolt for attaching compatible cameras, such as close-circuit television (CCTV) or security cameras, in-vehicle camera systems, POV cameras, point-and-shoot cameras, camcorders, or any device with a 1/4''-20 threaded pattern. The 4-hole drill-base mount is made of strong aluminum, and is ideal for environments where a more permanent solution is desirable, such as in a workshop or in retail. This mount can also be screwed directly into the floor of a car or truck. (Warning: Drilling into the vehicle's floor may damage the vehicle. Use caution and consult a mobile install professional to avoid drilling into any sensitive vehicle components.) Bend the 22'' adjustable arm and rotate the swivel ball adapter head for 360° rotation for exact positioning of the camera.
