The RAP-S-KNOB7U consists of a 5/16"-18 female threaded security knob, nut and key knob. The RAP-S-KNOB7U replaces all knobs on 2.25"/3.38" diameter D/E size arms and mounts. The RAP-S-KNOB7U offers the ideal amount of leverage to properly tighten your mount to prevent slippage in heavy chop or in extreme vibration environments. With an emphasis on aesthetics and function, the RAP-S-KNOB7U 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, the additional peace of mind and tamper resistance comes at a very affordable price. The RAP-S-KNOB7U is the perfect accessory for keeping your mounted electronic device safe from theft and tampering.

Customer Reviews (4.6 / 5 · 5 reviews)

Carter ★★★★★

I was a bit skeptical about needing a security knob for my mount, but the included nut and key knob make it super easy to lock down the gimbal plate. The 5/16"-18 threading is precise, and the whole assembly feels solid.

Ella ★★★★★

The 5/16"-18 thread fits perfectly on my swing arm, and the key knob gives me peace of mind that it won’t loosen during bumpy rides. Simple swap and solid feel.

Emma R. ★★★★★

Finally, a knob that stays put – the pin-lock mechanism is perfect for my truck's rough roads. The included nut and key knob make swapping accessories quick without tools.
