RAM® Pin-Lock™ 4 針安全旋鈕（適用於雲台支架）

The stud sizes give me real flexibility across my different mounts, and the locking mechanism feels solid enough that I don’t worry about the gimbal drifting mid-shot. Set it once and it’s stayed put through a whole day of bumpy filming.

The pin locks down tight with zero wobble once you crank it, and swapping between the stud sizes took me less than a minute. Perfect for keeping my gimbal gear from walking off between shoots.

I was a bit skeptical about how well a universal security knob would work, but the multiple stud sizes included made it a perfect fit for my gimbal bracket. It locks down tight with no wobble, and the 4-pin design gives me peace of mind that nothing will come loose on the job.
