The RAP-S-KNOB7-4U consists of a 5/16"-18 female threaded security knob, nut and key knob. The RAP-S-KNOB7 replaces the knob directly underneath the gimbal plate on all RAM® swing arm mounts. The RAP-S-KNOB7-4U 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-KNOB7-4U 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-KNOB7-4U is the perfect accessory for keeping your mounted electronic device safe from theft and tampering.

Harper I. ★★★★★

I was tired of my mount loosening on rough roads, but this threaded security knob with the key lock stays solid through every bump. The nut and key combo gives me peace of mind that nothing will shake loose.

Victoria ★★★★★

I’d been using a standard knob on my swing arm mount, but this 4-pin security version feels much more solid and makes it harder for the mount to accidentally loosen during a bumpy drive.

Amelia Q. ★★★★★

The key knob is a nice touch—makes it way easier to tighten or loosen the gimbal plate without fumbling around. I swapped out the old knob on my swing arm and it locks securely with no wobble.
