Middle Atlantic MRK-4436-NVR – 44RU 36" Deep NVR Security Rack

Product Overview

The Middle Atlantic MRK-4436-NVR is a 44-space, 36-inch deep floor-standing rack enclosure pre-configured for network video recorder (NVR) and physical security system deployments. Built on Middle Atlantic's MRK Series platform—known for fully welded construction and high seismic load ratings—this NVR rack arrives with power distribution, cable management, brush grommet panels, and vented doors included as a single part number. It is the preferred choice for installing contractors on multi-bay security and surveillance installations where structural integrity and efficient installation are priorities. The MRK-4436-NVR is suited for security operations centers, commercial building surveillance infrastructure, and multi-camera NVR system deployments requiring a purpose-configured rack enclosure.

Product Description

The MRK-4436-NVR delivers 44 rack units in a 36-inch deep fully welded steel enclosure designed to house NVR appliances, PoE switches, UPS systems, and associated security infrastructure. Fully welded construction provides greater rigidity and load capacity compared to knockdown rack designs, and the MRK Series carries a high seismic load rating that meets requirements for installations in seismic zones. The included 20A, 20-outlet corded power strip (PDT-2020C-NS) handles power distribution for high-draw NVR and switching equipment without requiring a separate PDU purchase. The enclosure includes a 64% open front door for front-access airflow, a 79% open split rear door for rear cable access and thermal exhaust, and a 64% open top for additional airflow and top cable entry. Cable management hardware includes a LACE-OP lacer strip, four straight lacer bars, two offset lacer bars, and 12 Velcro cable straps. Brush grommet panels (1-space and 2-space) provide clean cable passage points without requiring conduit. Front and rear cage nut rackrails with one pair of cage nut Z-rail adapters support both 6mm and 10-32 threaded fasteners. Racks are designed to gang together in multi-bay configurations when fully loaded. The package includes 100 6mm threaded cage nuts and rack screws, 50 10-32 threaded cage nuts and rack screws, side panels, and leveling feet.
