RAM® Pin-Lock™ B尺寸插座臂替換用4針鑰匙

This little key fits perfectly into my existing security knob setup and the 4-pin pattern aligned without any fuss. Saved me from having to buy a whole new mount system.

Finally got my replacement keys and they click into the lock mechanism with a satisfying snap. The plastic feels sturdy enough to handle daily adjustments on my equipment.

The replacement key fits the 4-node security pattern exactly, and I like that it’s a solid knob instead of a flimsy flat key. Swapped it in under a minute and it turns the socket arms smoothly, no wobble.
