This product is designed to be used with any of the "B" sized socket arms (see Related Products below). It consists of a 1/4"-20 female threaded security knob and key knob, which replaces the knob on the 1" diameter B size arms and mounts.

The RAP-S-KNOB3U is low profile so it only adds a small amount of additional bulk to your system when compared to the standard knob, but gives you great peace of mind becuase it is tamper resistant and keeps your device safe.

• Material: High Strength Composite

Note: The "U" in the part number reflects product packaged in poly bag. Mount not included with purchase.
