Middle Atlantic FRM Dstand 48WX75H Fltwall A3HPL BLK - FM-DS-4875FW-A3B

Middle Atlantic FM-DS-4875FW-A3B Designer Series Flat-Wall Rack Frame

Overview

The FM-DS-4875FW-A3B is a Middle Atlantic Designer Series rack frame configured at 48U wide by 75 inches tall, finished in black A3 High Pressure Laminate (HPL). The flat-wall (FW) designation means this frame is built to mount flush against a wall surface rather than as a fully freestanding enclosure — the right call for AV equipment rooms, security head-end closets, and commercial installations where floor footprint is constrained and a clean architectural appearance is required. The A3 HPL finish gives the exterior a durable, scratch-resistant surface that holds up in professional install environments without the wear issues of painted steel. If you are building out a Middle Atlantic rack system in a wall-mount configuration, the FM-DS-4875FW-A3B provides the outer frame structure into which standard Designer Series interior components — shelves, drawers, panels, and rack accessories — are integrated.

Compatibility

This frame is part of the Middle Atlantic Designer Series ecosystem. It accepts standard 19-inch rack-mount equipment across the full 48U of usable rack space. Interior components from the Middle Atlantic Designer Series — including fixed and vented shelves, blank panels, power strips, and cable management hardware — mount directly to the frame's vertical rack rails. The A3 HPL finish is a standard Designer Series surface option; confirm with your project specifications that A3 matches adjacent furniture finishes before ordering, as Middle Atlantic offers multiple HPL patterns. For network rack enclosures or fully enclosed versions of this footprint, compare against Middle Atlantic's enclosed Designer Series cabinet variants. Pair with compatible rack power distribution units and cable management for a complete installation.

Installation Notes

Flat-wall mounting requires confirmed wall-structure load capacity adequate for the frame weight plus all installed equipment. Coordinate anchor point locations with the frame's pre-drilled mounting pattern before rough-in. Verify rack rail spacing (standard EIA 19-inch) against your deepest chassis for clearance prior to final fit-out.
