Gibraltar SC-GCA 18-inch Cymbal Boom Arm with Grabber Clamp

The SC-GCA is an 18-inch cymbal boom arm fitted with a standard grabber clamp that attaches to an existing cymbal stand. It lets a drummer add an extra crash, splash, or effects cymbal without setting up a separate stand. The arm tube is 12.7 mm in diameter and clamps onto standard stand sizes.
