Description
The RAM Pin-Lock Medium Double Socket Arm for B Size 1" Ball is a standard-length RAM double socket arm with an integrated Pin-Lock security knob. It connects two RAM B Size 1" ball components, such as a mounting base and device holder, while adding tamper resistance compared to a standard adjustment knob.
This arm is a useful option for vehicles, fleets, work equipment, public-facing installations, or other mounting setups where added security is preferred without significantly increasing the size of the mount.
