The SC-4425MB Mini Cymbal Boom Arm, allows you to add a crash or splash cymbal to your set up, without having to add another stand. Connect it to a rack or existing cymbal / tom stand with a multi clamp, and position the cymbal exactly where you need it. This light weight boom has a 10” down tube, with a 7/8” diameter. The 12” hideaway boom arm is adjusted with a single point boom tilter where minimal adjustments are required.
