Pin-Lock™ Security Knob for C Size Socket Arms

RAM Mounts' features a 5/16"-18 Female threaded security knob and key knob designed to replace the standard knobs on 1.5-inch C Size arms and mounts.

The Pin-Lock™ security knob provides leverage for securely tightening your mount and helps prevent slippage in environments with heavy chop or vibration. Its low-profile design adds minimal bulk compared to the standard knob.

The RAP-S-KNOB5U provides added tamper resistance and security for mounted electronic devices.
