Middle Atlantic WMRK-4548 – 45RU 48"D Wall-Mount Rack Frame

Product Overview

The Middle Atlantic WMRK-4548 is a 45RU, 48-inch-deep wall-mount rack frame designed for mounting deep equipment in applications where floor-standing racks are not practical. It accommodates high-density AV and IT gear in shallow wall cavity installations, telecom rooms, and dedicated wall-mount equipment bays. Common search terms include 45U deep wall-mount rack frame, Middle Atlantic 48-inch wall rack, and wall-mount equipment rack for AV and IT.

Product Description

The WMRK-4548 provides 45 rack units of mounting space on a wall-mount frame with 48 inches of equipment depth — the deepest configuration in Middle Atlantic's wall-mount rack line. This depth accommodates server-class equipment, deep AV processors, and dense switching gear in wall-mount installations that would typically require a floor-standing rack. The open frame design maximizes airflow around installed equipment, which is critical in wall-mount environments where enclosed cabinets can trap heat. The frame mounts directly to structural wall surfaces and is rated for the full populated weight capacity of a 45U deployment. Mounting rails conform to EIA 19-inch standards and accept all standard rack-mount equipment. The WMRK-4548 is a frame-only product and ships without doors or side panels, keeping installation weight lower and simplifying initial build-out. Optional Middle Atlantic accessories including horizontal cable management and blanking panels are compatible with this frame. This rack is suitable for locations where floor space is unavailable or where equipment must be positioned at a fixed wall height for operational reasons. Available for purchase and project quoting at creationnetworks.net.

Technical Specifications

Frequently Asked Questions

What does "frame only" mean for the WMRK-4548?

Frame only means the rack ships without doors or side panels. The mounting rails and structural frame are included, but no enclosure panels. This reduces installation weight and is appropriate for open equipment rooms where physical security panels are not required.

Can 48-inch-deep equipment be mounted in the WMRK-4548?

The 48-inch depth refers to the available equipment mounting space. Standard rack-mount equipment is typically 1-2U in height with varying depths; always verify specific equipment depth against available clearance before installation.

How is the WMRK-4548 mounted to the wall?

The WMRK-4548 is designed for direct mounting to structural wall surfaces. The frame includes wall-mount attachment points. Always mount to structural studs or use appropriate wall anchors rated for the loaded weight of the rack.

Is airflow adequate in a wall-mount open frame configuration?

Yes. The open frame design of the WMRK-4548 allows passive airflow on all sides of installed equipment, which is generally superior to enclosed cabinet wall mounts for thermal management.

What accessories are compatible with the WMRK-4548?

Middle Atlantic horizontal cable management panels and blanking panels are compatible. Additional accessory compatibility should be verified against the WMRK frame dimensions.
