RAM Mount 1" Ball Universal Mount Kit – Round Base, Double Socket Arm & 6-1/4" x 2" Plate (RAM-B-111)
A complete, flat-surface mount kit built for marine electronics. The RAM-B-111 combines a 2.5" round base, a 1" double socket arm, and a 6-1/4" x 2" rectangular plate into one ready-to-install system — all constructed from black powder-coated marine-grade aluminum that holds up in saltwater environments.
The rectangular plate is pre-drilled with multiple hole pattern combinations to match a wide range of marine electronics and mounting brackets, including GPS chartplotters, VHF radios, CB and ham radios, and gimbal brackets. The 1" rubber ball-and-socket joints at both ends of the arm give you near-infinite tilt, swivel, and rotation adjustment so you can dial in the perfect viewing angle and lock it down.

Parts Desk Insights
Best suited for mounting electronics directly to a flat deck, helm console, or bulkhead surface where the device uses a standard gimbal bracket or bolt-pattern mount rather than a RAM cradle. The 6-1/4" x 2" rectangular plate gives you more mounting surface and hole-pattern flexibility than a diamond adapter, making this the right kit when you’re working with a GPS chartplotter or radio that has its own bracket. The marine-grade aluminum construction makes it a step up in durability for permanent offshore or coastal installations. If your device uses a RAM cradle instead of a bracket, the RAM Mount 1" Ball Mount Kit with Diamond Adapter (RAM-B-138U) is the better match. For rail mounting instead of flat surface, pair the RAM Mount 1" Ball Rail Base with the RAM Mount Standard Double Socket Arm for 1" Balls.
