Universal 2 Hole 20mm Ball Mounting Base 38mm AMPS Pattern (10-21005)

Every good device mount setup starts with a solid foundation, and this is it. Westin's 2 hole 20mm ball mounting base is the anchor point that the rest of the Adventure Mount system builds on, pairing an extruded aluminum top base with steel mounting brackets so the ball stays planted no matter how rough the road gets. It carries the standard 20mm ball that Adventure Mount arms clamp onto, which means you can run a phone, a tablet or a camera off it and reconfigure the whole thing later without touching the base.

The mounting plate uses the 2 hole 38mm AMPS pattern, so it drops onto a Westin vehicle specific dash base or onto any other AMPS pattern surface you already have in the cab. The compact footprint is the real advantage here, since it lets you claim a mounting point in tight dash and console areas where a bigger plate simply will not sit flat. Mounting hardware and weld nuts are included, the finish is a corrosion resistant black powder coat, and the whole install is a basic hand tool job.
