Middle Atlantic Pair of Side Panels Fits 42 DP Racks ***Drop Ship Only*** - SPN-44-423

Middle Atlantic SPN-44-423 44U Rack Side Panels

Overview

The Middle Atlantic SPN-44-423 is a pair of solid steel side panels designed for 44U rack enclosures with a 42-to-43-inch depth. If you are closing out an open-frame or partially enclosed Middle Atlantic rack for cable management, airflow control, or physical security reasons, these panels drop into place without tools — the lift-on/off design with integrated internal handles makes field installation and future access straightforward. At 90 lbs per pair, they are heavy-gauge construction, not sheet-metal trim pieces. Dimensions run 77 to 83.1 inches in height and 42 to 43 inches in depth, covering the full side profile of a standard 44U enclosure.

Compatibility

The SPN-44-423 is designed specifically for Middle Atlantic rack enclosure families at 42-to-43-inch depth: WRK, MRK, VMRK, VRK, and DRK series. Verify your enclosure's listed depth before ordering — Middle Atlantic produces side panels in multiple depth variants, and a mismatch means the panel will not seat correctly on the lift-on rails. These panels are not cross-compatible with other manufacturers' enclosures or with Middle Atlantic racks outside the 42-to-43-inch depth range. If you are building out a full rack enclosure system, confirm the enclosure series and depth against this panel's spec before specifying it on a project.

Installation Notes

Installation is tool-free via the lift-on/off mechanism with internal handles — panels seat onto the enclosure frame and lift clear when access is needed. The 90 lb combined weight means two-person handling is advisable during initial rack build-out, particularly in tight equipment rooms. No additional hardware or fasteners are required for standard panel mounting. Black finish matches standard Middle Atlantic enclosure colorways across the compatible series.
