RAM Mount 1" Ball Universal Mount Kit – Composite, Double Socket Arm & 6-1/4" x 2" Plate (RAP-B-111)
A complete, flat-surface mount kit for marine electronics, built from RAM’s high-strength composite material. The RAP-B-111 pairs a standard double socket arm with a 6-1/4" x 2" rectangular plate, giving you a versatile, multi-hole mounting surface that fits a wide range of GPS chartplotters, VHF radios, CB and ham radios, gimbal brackets, and other electronics.
The rectangular plate includes the universal AMPS hole pattern plus multiple additional pre-drilled hole combinations, so it adapts to most standard device mounting footprints without drilling. The 1" rubber ball-and-socket joints at both ends of the arm deliver near-infinite tilt, swivel, and rotation adjustment — dial in your angle and lock it down.

Parts Desk Insights
Best suited for lighter-duty or budget-conscious installations where the full corrosion resistance of marine-grade aluminum isn’t required — ideal for freshwater boats, protected coastal use, or cabin/interior mounting locations. The composite construction keeps weight and cost down while still delivering the full RAM ball-and-socket adjustability. The 6-1/4" x 2" plate is the right choice when your device uses a standard gimbal bracket or bolt-pattern mount rather than a RAM cradle. If you need the added durability of marine-grade aluminum for a permanent offshore installation, step up to the RAM Mount 1" Ball Universal Mount Kit – Aluminum (RAM-B-111). 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 fit. For rail mounting, pair the RAM Mount 1" Ball Rail Base with the RAM Mount Standard Double Socket Arm for 1" Balls.
