The RAP-S-KNOB3U consists of a 1/4"-20 female threaded security knob and key knob. The RAP-S-KNOB3U replaces all knobs on 1" diameter B size arms and mounts. The RAP-S-KNOB3U 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-KNOB3U 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-KNOB3U is the perfect accessory for keeping your mounted electronic device safe from theft and tampering.

George E. ★★★★★

The 1/4"-20 threaded design swaps in cleanly on my B size arm, and the key knob gives me peace of mind against theft. Tightened it once and it hasn't budged since.

Michael ★★★★★

Finally, a knob that won't back off on its own mid-ride—the 1/4"-20 thread seats perfectly and the key knob adds real peace of mind when leaving the rig parked. Took about thirty seconds to swap out on my B size arm, and the locking action is crisp without being stiff. Exactly what I needed to stop

Eva ★★★★★

The keyed design gives me peace of mind that my tablet mount won't walk away, and swapping out the old knob took less than five minutes.
