Middle Atlantic WMRK-4236SVR-AB – 42SP Configured Server Rack Add-a-Bay

Product Overview

The Middle Atlantic WMRK-4236SVR-AB is a 42-space, 36-inch deep configured server rack Add-a-Bay built for multi-bay equipment rooms, data centers, and raised-floor environments where rack capacity needs to expand alongside an existing WMRK enclosure. As an Add-a-Bay unit, it gangs directly to an installed WMRK bay, letting integrators grow a server rack installation without duplicating side panels or floor space. The enclosure arrives configured with cage nut rackrail, perforated doors, a vented top, and a 20A power strip, reducing on-site assembly time for commercial deployment. It is a practical choice for IT and facilities teams standardizing on the Middle Atlantic WMRK series.

Product Description

The WMRK series was designed specifically for mounting deep equipment in a standard 24-inch wide enclosure optimized for raised-floor installation. The fully welded steel frame provides the strength and stability needed for heavy server loads, and racks gang together even when fully loaded, which simplifies phased expansion in a live equipment room. This configured server model includes two pairs of adjustable cage nut rackrail and one pair of Z-rail sidemount adaptors set up to accept servers and slide kits from all leading manufacturers. Perforated front and rear doors satisfy most server manufacturer warranty specifications for airflow, and the included vented top supports passive heat evacuation. A pre-mounted vertical lacing strip on this 42-space model keeps cable management organized from day one, while numbered rackspace increments speed equipment mounting during installation. Middle Atlantic also includes leveling feet, 100 6mm cage nuts with hardware, a 20-outlet 20A power strip, and the ganging hardware required to join this Add-a-Bay to an adjacent WMRK enclosure. For AV integration projects that pair head-end servers with control processors and network switching, this rack provides a single, serviceable home for the full equipment stack.
