Help

Use the selected holder’s specified attachment screws and nuts, including the correct screw length for its adapter connection. RAM holders commonly include their own assembly hardware; separate holder attachment fasteners are not listed as included here. Choose a mounting base that suits your mounting surface and the full holder, case and device load.

Assess reach, vibration and mounting-surface strength as well as the component rating. Check joints and fasteners before use.

Compatibility

The lower socket accepts a 1.5-inch C-size RAM ball. The supplied round plate attaches to a holder with a matching AMPS pattern. A 1-inch B-size ball does not fit this C-size arm. Check the chosen holder’s device and case dimensions separately.
