Help

Measure the rail before ordering and use the correct included inserts. The base requires the supplied hex key for installation. Follow the Torque base installation instructions and inspect the fasteners regularly. Screws for attaching a holder to the diamond plate depend on the holder; use its specified hardware and screw length. These holder screws are not listed as included in this bundle.

Assess the full holder, case and device load, mounting surface, reach and vibration against the rating. Check all joints and fasteners before use.

Compatibility

Choose a flat-backed holder with a matching 2-hole AMPS connection and suitable fasteners. A holder with an integrated 1-inch B-size ball can connect directly to the arm instead of the included diamond plate. C-size balls require a matching C-size arm. Check the selected holder’s device and case dimensions separately.
