  • 1 x RAM Pin-Lock Nut for D & E Size Arms (RAP-S-NUT5U)

The RAP-S-NUT5U features a 1/2"-20 female threaded security nut and key knob. This component replaces the knob on 2.25"/3.38" diameter D/E size arms and mounts.

The RAP-S-NUT5U offers the ideal amount of leverage to properly tighten your mount to prevent slippage in heavy chop or in extreme vibration environments. 

The RAM Pin-Lock solutions are built to handle the toughest environments where RAMMounts are commonly used. By adding a little extra bulk to your setup, you can rest assured knowing your device is safe from theft or tampering. 

High Strength Composite 

For the highest security, apply thread-locker liquid to the internal threads of the RAM® Pin-Lock™ Security Nut prior to installation. 

      The "U" in the part number reflects product packaged in poly bag.

        RAM Pin lock - Excellent!

        So easy to use yet so secure. Allows free use of RAM mount for adjustment, but does not allow removal. Awesome way to secure your RAM investment.
