Ram Combination Pin-Lock Security Knob and Key for 1.5 inch diameter C Size Arms.
The Ram Combination Pin-Lock consists of a 5/16 inch-18 female threaded security knob and key knob.
It replaces all knobs on 1.5 inch diameter C size arms and mounts and offers the ideal amount of leverage to properly tighten your mount to prevent slippage in heavy chop or extreme vibration environments.
With an emphasis on aesthetics and function the security knob is low in profile and only adds 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 and with additional peace of mind and tamper resistance which comes at a very affordable price, it is the perfect accessory for keeping your mounted electronic device safe from theft and tampering.
