RAM® 帶黃銅嵌件的鑰匙鎖旋鈕 for 擺臂

Finally got around to swapping out the old plastic knob on my swing arm, and this one feels rock solid. The brass insert threads in with a satisfying, snug fit, and the locking action is noticeably crisp. Exactly what I needed to stop things from vibrating loose on the road.

The brass insert threads smoothly into my swing arm, and the key lock keeps it from loosening during bumpy rides. Installation took maybe two minutes, and it feels much more secure than the standard thumbscrew I was using before.

The key lock mechanism engages with a satisfying click, and the brass threads feel much more durable than the plastic knobs I've used before. It's a simple upgrade that makes adjusting my swing arm setup feel far more secure.
