Middle Atlantic RSH4A3RW – Custom 3U Wide Rackshelf Enclosure, 15.5" Deep

Product Overview

The Middle Atlantic RSH4A3RW is a wide-format custom 3U rack shelf enclosure with a 15.5" shelf depth, built to mount non-rackmount AV components in standard 19" racks. It occupies the middle ground of the 3U RSH4A depth range — deeper than the 11.5" shallow models, shorter than the 17.5" full-depth version — for components that need real shelf depth in racks that cannot spare the maximum. The black brushed and anodized face plate is custom cut around your equipment for a finished rack appearance.

Product Description

Choosing a rack shelf comes down to matching shelf depth to both the component and the rack, and 15.5" is often the practical sweet spot. The RSH4A3RW delivers that mid-depth in a wide-format 3U custom shelf enclosure: in the model code, 3 is the rack-unit height, R is the 15.5" depth, and W marks the wide face plate format for broader chassis. That combination suits mid-depth hi-fi components, preamplifiers, and media servers that overhang an 11.5" shelf but do not require the full 17.5" platform. As with every RSH4A custom rackmount shelf, the black brushed and anodized face plate is cut to the exact dimensions of the component being installed, closing the 19" rack opening cleanly around the device. The result reads as purpose-built rackmount equipment, with front-panel controls, displays, and IR windows fully usable through the cutout. The component itself is never drilled or modified, so manufacturer warranties survive the installation and equipment swaps down the road stay simple. The anodized finish is consistent with Middle Atlantic blank panels and faceplates, keeping mixed racks visually uniform. Projects needing maximum shelf depth in the wide format should look at the RSH4A3XW 17.5" deep wide rack shelf, while shallow wall racks are better served by the RSH4A3SW 11.5" deep wide shelf.

Key Features

• Mid-Depth 15.5" Shelf — Bridges the gap between shallow 11.5" and full 17.5" models for components that need moderate shelf depth.
• Wide-Format Design — Accommodates broader component chassis than the standard-width RSH4A shelves at the same 3U height.
• Custom-Cut Anodized Face Plate — Black brushed and anodized plate machined around your specific component for an integrated finish.
• Standard 19" Rack Mounting — Installs in three rack spaces of any standard rack or enclosure with no rack modification.
• No Component Alteration — Equipment is never drilled or permanently attached, preserving warranty coverage.
• Front-Panel Visibility — Controls, displays, and IR receivers stay accessible through the precision cutout.
