Middle Atlantic MRK-4431-DVR – Pre-Configured DVR Security Rack, 44 RU

Product Overview

The Middle Atlantic MRK-4431-DVR is a pre-configured DVR equipment rack built for surveillance recording systems and security head-end installations in commercial facilities. This 44 RU, 31-inch deep MRK Series enclosure arrives with power distribution, cable management, and ventilated doors already included, so installing contractors can rack recording hardware without sourcing accessories separately. With its fully welded steel frame and high seismic load rating, this security rack enclosure is a dependable choice for government, campus, and enterprise security deployments.

Product Description

Specify the MRK Series when you need an equipment rack built to perform like a workhorse on larger-scale projects. The MRK-4431-DVR is factory-configured for DVR and video surveillance recording equipment, pairing 44 rack spaces of capacity with a 31-inch usable mounting depth in a 22-inch wide frame. Fully welded construction delivers the strength and rigidity that multi-bay installations demand, and MRK racks gang together even when fully loaded, which simplifies phased build-outs in security equipment rooms. Airflow is addressed with a 64% open front door, a 79% open split rear door, and a 64% open top, keeping recording appliances and storage arrays ventilated around the clock. A 20A, 20-outlet corded power strip (PDT-2020C-NS) is included for clean, consolidated power distribution to rack-mounted devices. Cable management is handled by an included LACE-OP lacer strip, four straight and two offset lacer bars, and twelve hook-and-loop straps, while 1-space and 2-space brush grommet panels manage cable pass-through without dust intrusion. Front and rear 10-32 threaded rackrail with 100 included rack screws accommodates standard EIA 19-inch equipment, and side panels plus leveling feet complete the enclosure. The series also carries seismic certification, making it suitable for jurisdictions and facilities that require seismic-rated AV and security infrastructure. For integrators handling commercial AV installation alongside security work, this rack keeps both disciplines on a common, proven mounting platform.
