UA 25mm Ball Socket to 4-Hole AMPS Adapter


This plate is the easiest way to mount any device that has a 4-hole AMPS mounting pattern directly to a RAM Mount style 1” ball.

This is ideal for a compact installation of Garmin zumo or TomTom Rider motorcycle GPS devices on your bike. The 4-hole AMPS pattern also matches the genuine Garmin Montana and inReach AMPS cradles as well as a huge range of other manufacturers’ devices.

The 4-hole AMPS pattern dimensions are approximately 31mm x 38mm (1.188” x 1.496”). The holes are arranged in a rectangular pattern and has been adopted as an industry standard for mounting electronic devices.

The socket slots securely over 25mm (1 inch) balls and is compatible with 25mm ball mount systems from RAM Mount, SW-Motech and many more.

The mount is secured into place by tightening the collar which applies pressure on the surface of the ball.
