Middle Atlantic WMRK-4236 – 42U 36" Wall-Mount Rack Frame

Product Overview

The Middle Atlantic WMRK-4236 is a 42U wall-mount rack frame with 36-inch depth, designed for AV and IT installations where floor-standing racks are impractical and wall-hung equipment mounting at high rack unit density is required. At 42U, this is among the highest-capacity configurations in the WMRK wall-mount series and supports a broad range of AV distribution, IT networking, and infrastructure equipment. AV integrators and IT managers searching for a "42U wall-mount rack frame" or "deep wall-hung rack 36-inch 42U" will find the WMRK-4236 suited for wiring closets, mechanical rooms, and secondary AV equipment locations.

Product Description

The WMRK-4236 is a frame-only wall-mount rack, meaning it ships without side panels, doors, or top caps. This allows the integrator to specify only the enclosure components the installation requires, reducing cost and weight on the wall mount. The 42U capacity provides substantial rack space for patch panels, managed switches, control systems, media distribution equipment, and signal processing gear in a single wall-hung unit. The 36-inch depth accommodates standard 1U to 4U AV and IT equipment including most networking gear, AV over IP equipment, and distribution amplifiers. Wall-mount installation is achieved through the frame’s integrated mounting flanges, engineered to transfer rack load to structural wall members. Professional installation by a licensed contractor is recommended to ensure wall backing and fastener specifications meet the fully loaded weight requirements. The open-frame design allows access for cabling and equipment maintenance without removing panels, making the WMRK-4236 practical for regularly serviced wiring closet environments. Compatible Middle Atlantic accessories integrate directly with the WMRK rail system and are available from Creation Networks.
