Middle Atlantic MRK-4442PROLRD – 44SP 42"D Multibay Rack PRO LRD

Product Overview

The Middle Atlantic MRK-4442PROLRD is a 44-space, 42"-deep multibay gangable rack with lever-release door and PRO-level integrated cable management, built for high-density AV and IT equipment rooms requiring maximum space utilization and structured cable organization. The MRK (Multibay Rack) series is designed for side-by-side gangable configurations, allowing multiple units to join into a continuous rack bay without gaps. The PRO designation adds enhanced vertical and horizontal cable management provisions over the base MRK configuration.

Product Description

The MRK-4442PROLRD delivers 44 rack spaces in a 42"-deep enclosure — the deepest configuration in the MRK line, accommodating high-density servers, network switches, large AV processors, and UPS systems. The lever-release door (LRD) mechanism allows the front door to be removed quickly without tools, providing unobstructed front-panel access during installation and maintenance. The PRO cable management package includes integrated vertical cable managers on both sides of the interior plus additional horizontal management provisions, supporting high-count cable runs common in dense AV and IT builds. The gangable design allows adjacent MRK units to be joined with gang hardware, creating a continuous multi-bay enclosure without visible gaps between racks. The steel frame handles the full equipment load across all 44 spaces. Front and rear 10-32 threaded rails are standard. Available through Creation Networks at creationnetworks.net.
