Middle Atlantic MRK-4442LRD – 44SP 42"D Multibay Rack with LRD
Product Overview
The Middle Atlantic MRK-4442LRD is a 44-space, 42"-deep multibay gangable rack with lever-release door, built for high-density AV and IT equipment rooms where fast front-access and maximum rack depth are required. The lever-release door (LRD) allows tool-free front door removal for unobstructed equipment access. The MRK series is designed for gangable side-by-side multi-rack configurations in larger equipment rooms and centralized AV infrastructure deployments.
Product Description
The MRK-4442LRD delivers 44 rack spaces in a 42"-deep enclosure — the maximum standard depth in the MRK line, supporting full-depth servers, high-density network switches, large UPS units, and professional AV processors. The lever-release door mechanism eliminates the need for tools to remove the front door, providing full unobstructed access to all 44 front-panel positions during installation and maintenance. The gangable frame design uses Middle Atlantic's side-joining hardware to connect adjacent MRK units into a seamless multi-bay enclosure. Standard cable management provisions are included in the configured build. Front and rear 10-32 threaded rails accept standard 19" rack hardware. For integrators requiring enhanced vertical cable management in addition to the LRD, the MRK-4442PROLRD adds integrated vertical cable managers. Available through Creation Networks at creationnetworks.net.
