RAM® 雙球型支架 附1/4-20公螺紋 - B尺寸長型

The 2.5" AMPs plates lined up perfectly with my existing gear and the double ball setup feels rock solid even with a heavier camera attached. I love how adjustable it is—once tightened down, there's zero wobble.

The long B-size arm really gives you the reach you need to position a camera or device exactly where you want it, and the 2.5-inch AMPS plates match up perfectly with what I already had. I've had it holding a heavy action cam on bumpy trails for two weeks now and nothing has slipped or wiggled loose

The AMPS hole pattern on both plates made it easy to mount my camera directly to my existing setup. The arm length gives me just enough reach to position it perfectly without any wobble.
