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. At a fraction of the cost of currently available keyed locking knobs, the additional peace of mind and tamper resistance comes at a very affordable price. The included threaded key knob replaces the gimbal knob, assuring your mounted electronic device is safe from theft and tampering. The security Pin-Lock kit is compatible with all RAM No-Drill and drill down laptop vehicle kits.
