The CLH-930 Uni-Lock Closed Hi-Hat Boom Arm mounts a pair of cymbals in practically any location around the drum kit. Useful for standard closed hi-hat cymbals or creative cymbal stacking, its simple spring-action mounting system allows you to choose the amount of "wash" in your mounted cymbals with an easy turn of the top washer. Its Uni-Lock tilter gives a nearly limitless option for angle adjustment, while the solid Hideaway Boom Arm allows for positioning as close or as far as your reach requires.
