SKB's 1SKB-R104W Compact Rolling Rig features a standard 10U top and 4U front and rear rack rails. It also includes a special one-touch pull handle and back lid mounted wheels for easy transport, as well as a redesigned exterior that allows this newer Rig to easily stack with existing standard Roto-Racks and the recently updated Roto Rolling Racks. Featuring an injection-molded top, this Rolling Compact Rig also comes standard with TSA-accessible locking latches that secure the lid to the top of the rig.
