## Long description

The RAM Mounts Key Lock Knob with Brass Insert is designed for C size (1.5") socket arms and features a brass 5/16"-18 threaded insert.

Advantages

How to use
Thread the knob onto the 5/16"-18 stud of the C size socket arm until the socket and ball are positioned as required. To reposition, disengage the knob’s threading as needed, adjust the arm, then tighten the knob to lock the mount in place. Use moderate hand force to avoid over-tightening and ensure the brass insert and threads engage smoothly.
Usage recommendations
For best performance, inspect threads and the brass insert periodically for wear or corrosion, especially in marine or high-moisture environments. Replace the knob if threads become stripped or if the insert loosens to maintain secure mounting.
