The Rock Steady surface base allows you to turn any two existing fasteners into a secure and stable platform. Don't trust one screw holding your HD Camera in a high speed, high vibration environment. Simply attach your camera to any 2 fasteners that are between 2"-5" apart. Just attach the base directly over a inspection cover or wing tip. A rubber gasket is included to protect your painted surface. Two included flush washers fit the base plate slots and accept most #6 - #10 size screws. When the camera mount is not being used, the surface base is low profile. Attach numerous bases to your aircraft for quick change camera locations. The surface base has been tested up to 350 kts. This surface base is compatible with all Rock Steady mounts.
