Regular price$ 8.99


The RAM-B-238U ball base consists of a 1" B size rubber ball connected to a 2.43" x 1.31" diamond plate.

This diamond ball base is made of powder-coated, marine-grade aluminum for durability and reliability in the most demanding environments.

This diamond ball base is compatible with a wide variety of RAM® device holders and cradles.

Ball and socket technology allows for near-infinite adjustability since the diamond plate features two holes that measure 1.912" from center to center, matching the industry standard AMPS hole pattern.

The most common screw sizes needed for the holes on this ball plate are #8, #10, M4, and M5 screws. However, if you are pairing this with any RAM® Holder, the holder will come with the necessary hardware to connect to your mount.
