SKB 4U 30-Inch Deep 3RR Shock Rack Case – Maximum Protection for Mission-Critical Rack Equipment

Product Summary: Designed for demanding military, industrial, broadcast, and telecommunications applications, the SKB 4U 30-Inch Deep 3RR Shock Rack Case combines a rugged roto-molded shell with a fully removable shock-mounted rack chassis to protect sensitive electronics during transport and deployment.
