MRK-4426 shown. The narrow design of the 22" wide MRK gangable rack enclosure lends itself well to large-scale, multi-bay jobs. The MRK should be used when multiple racks need to be joined, or when open sides are desirable for easy access to cables and components. The slim, space-saving design is ideal whenever floor space is a consideration. A standard, locking rear door incorporates a spring-loaded latch to keep the door closed and prevent tampering.
