Composite connecting arm (medium) with pin-lock fuse and adapter (5-pin) - (1.5 inch)

The RAM Double Socket Arm with RAM Pin-Lock Security Knob consists of a composite C size double socket arm and combination Pin-Lock security nut and key knob for theft deterrence. RAM Pin-Lock security solutions are designed to withstand the harshest environments where RAM Mounts are commonly used. With an emphasis on aesthetics and function, RAM security nuts/knobs are low profile and only add a small amount of additional bulk to your system when compared to the standard knob included.
