Middle Atlantic MRK-4042 – 40SP 42"D Multibay Configured Rack

Product Overview

The Middle Atlantic MRK-4042 is a 40-space, 42"-deep multibay gangable configured rack built for AV and IT equipment rooms that require a high-density, deep enclosure capable of joining with adjacent rack units. The MRK series supports side-by-side gangable installations, making it the preferred choice for multi-rack bays in larger equipment rooms and data-adjacent AV environments. At 40 spaces and 42" depth, this rack accommodates deep servers, network switches, AV processors, and UPS units in a single enclosure.

Product Description

The MRK-4042 provides 40 rack spaces in a 42"-deep gangable enclosure, configured with Middle Atlantic accessories to reduce field integration time. The 42" depth is the deepest standard configuration in the MRK line, accommodating equipment that would not fit in 25"–32" deep racks — including full-depth servers, high-density network switches, and large UPS units. The gangable design uses Middle Atlantic's side-joining hardware to connect adjacent MRK units into a seamless continuous bay without visible gaps between enclosures. The configured build includes horizontal cable management and power provisions pre-installed at the factory. Front and rear 10-32 threaded rails accept standard 19" rack hardware. The steel frame handles full equipment loads across all 40 spaces. Available through Creation Networks at creationnetworks.net.
