Product Overview
The Middle Atlantic MRK-3731LRD is a 37-space, 31-inch-deep pre-configured multibay AV rack with a lever-release door for tool-free front access. It is designed for AV integration projects requiring a gangable rack enclosure that ships ready for equipment loading without additional configuration. The 37U interior provides more capacity than a standard 36U rack, accommodating additional patch space or a dedicated cable management unit. Gangable construction allows multiple MRK bays to be joined side-by-side for a continuous rack row.
Product Description
The MRK-3731LRD is part of Middle Atlantic's MRK (Millwork Rack) series, a product line engineered for AV furniture integration and finished equipment room installations where appearance and structural consistency matter. The 37-space interior gives integrators additional rack unit flexibility over standard 36U enclosures, often used to accommodate dedicated horizontal cable managers or blanking panels without sacrificing usable equipment space. At 31 inches of interior depth, the MRK-3731LRD handles the majority of professional AV gear — amplifiers, signal processors, video distribution equipment, and networking hardware — without the excess depth of a 35- or 40-inch enclosure. The lever-release door (LRD) detaches from the front without tools, an important feature in dense multi-bay installations where a hinged door would impede adjacent bay access. Gangable construction allows the MRK-3731LRD to be mechanically joined to adjacent MRK bays, creating a unified rack row with consistent structural and visual properties. Internal cable management provisions are designed to support the higher cable counts typical of a 37U AV rack build. Pre-configured status means the rack ships ready to receive equipment, reducing on-site assembly time. The MRK series finish is suitable for exposed or semi-exposed equipment rooms in corporate, education, and hospitality environments. Available through Creation Networks at creationnetworks.net.
