RAM® Pin-Lock™ 替換用 7 針鑰匙，適用於 C 尺寸及旋轉臂

It was surprisingly easy to swap in this replacement key—it fits the C size arm’s security knob perfectly and the metal feels sturdy. I’ve had no issues with it locking or unlocking since I installed it.

The 7-pin pattern matches my existing knob exactly, so it slipped right in without any fiddling. Good to have this spare since losing the original would've been a real headache.

Picked up this as a spare for my existing security knobs, and the 7-pin pattern matched perfectly—no fiddling needed. The key has a solid, precise feel when turning, just like the original. Glad I can finally lock up my gear without hunting for that one specific key.
