RAM Mounts Composite Double Socket Arm, B-Size, Short, 61 mm (RAP-B-201U-A) is the connecting link of the RAM ball-and-socket system: it joins two RAM B-size (1") ball components – typically a ball base fixed in a vehicle, on a forklift or at a workstation and a device holder or cradle with a matching ball. With 61.5 mm (2.42") overall and 44.5 mm (1.75") between the sockets, it is a compact, low-profile arm for installations where the device should sit close to the base. A spring inside the arm keeps the sockets open for easy fitting, and turning the knob clamps both ball joints firmly at the angle you need.
