Middle Atlantic 42IN. Outside Depth Multibay Rack- Less Rear Door ***Drop Ship Only*** - MRK-4442LRD

Middle Atlantic MRK-4442LRD 44RU Open-Frame Floor-Standing Rack

Overview

The Middle Atlantic MRK-4442LRD is a 44RU, 42-inch outside-depth open-frame equipment rack built for AV and security system integrators who need substantial gear density without the weight or cost of a full enclosure. At 22 inches wide and 83.13 inches tall, it accommodates standard 19-inch panel equipment across 44 rack units — enough vertical space for NVRs, patch panels, power distribution, and switching in a single footprint. The frame-only configuration (no side panels, no rear door) means unrestricted rear cable access, which matters when you're pulling multiple conduit runs or managing dense structured cabling behind network video recorders and servers. USA-manufactured and TAA compliant, MRK-4442LRD suits government and public-sector deployments where domestic origin is a procurement requirement.

Compatibility

The MRK-4442LRD uses standard 10-32 threaded rack rails, compatible with the full range of Middle Atlantic rack accessories including PDUs, blanking panels, cable management rings, and shelf kits designed for the MRK series. The 19-inch panel width accepts all standard EIA-310-D rack-mount equipment. With 39.6 inches of usable depth (front-rail face to rear-rail face), it comfortably fits deep 1U/2U servers, NVR chassis, and UPS units that would otherwise require extended-depth cabinets. It is gangable, so multiple units can be bolted side-by-side for multi-bay deployments in larger security and surveillance equipment rooms. Confirm floor load ratings before deploying at full capacity — the UL-listed static load is 2,500 lbs, while the total weight capacity reaches 10,000 lbs under seismic conditions per ASCE 7-10.

Installation Notes

This unit ships at 171 lbs and is drop-ship only — plan for liftgate delivery and a minimum two-person installation crew. The open-frame design requires a conditioned, access-controlled equipment room or dedicated IDF/MDF space; without side panels or a rear door, it provides no physical security or dust protection on its own. Seismic certification to ASCE 7-10 applies when properly anchored per Middle Atlantic's seismic installation guidelines — anchor hardware and floor-mounting provisions are not included in the frame-only configuration. Confirm anchor bolt pattern against your raised floor or concrete slab before scheduling installation. For enclosed deployments, pair with a compatible rack enclosure or add Middle Atlantic side panels and door accessories separately.
