RAM Mount Standard Double Socket Arm for 1" Balls (RAM-B-201)
The connecting link in any RAM 1" ball mount system. This standard-length double socket arm has a 1" ball socket at each end and a spring-loaded mechanism that lets you pivot, tilt, and rotate your device to exactly the angle you need — then lock it down with a single knob. Once tightened, it holds firm against vibration and wave action.
At 3" socket-to-socket (3.69" overall), this is the standard reach arm — the most commonly used length for helm, dash, and rail mounting applications. It bridges any compatible 1" ball base to any compatible 1" ball device holder or cradle.

Parts Desk Insights
Best suited for helm and dash mounting setups where you need a moderate reach between a fixed base and a device cradle. This arm is the standard choice for most GPS chartplotter, VHF radio, and phone mount installations on boats. Pair it with a RAM Mount 1" Ball Rail Base or a round base on one end, and a device cradle on the other. If you need less reach in a tighter space, the RAM Short Double Socket Arm for 1" Balls is the compact alternative. For a complete ready-to-mount kit with base, arm, and plate already matched, see the RAM 1" Ball Mount with Double Socket Arm & Round Base.
