Bringing greater expansion possibilities to the Icon drum rack system, the RJ50 Mini Expansion Rail features a 6" section of Pearl's trademark square Aluminum rack rail. Each end features a fixed 1.5" bar clamp. This is exceptional as a joint for connecting two Icon racks, or simple expansions for mounting added accessories. Comes standard with two DC422A Hinged Memory Clamps to lock height into position and secure set-up parameters.
