RAM® Pin-Lock™ 스윙 암용 4핀 보안 노브

I needed a way to secure my tablet mount against theft, and this knob’s locking mechanism fits perfectly on the swing arm—no wiggle at all once tightened.

The key knob turns smoothly and locks with a satisfying click, way more secure than the plastic thumbscrews I was using before. It swapped onto my swing arm in under a minute, and now nothing’s going to vibrate loose on the trail.

Snapped right in place on my swing arm, and the 3/8"-16 threading was a perfect match for the existing mount. The key knob gives me peace of mind knowing the tablet won't walk away, especially at crowded job sites.
