Middle Atlantic RSH4A3S – Custom 3U Rackshelf Enclosure, 11.5" Deep

Product Overview

The Middle Atlantic RSH4A3S is a compact custom 3U rack shelf enclosure that mounts a non-rackmount component in a standard 19" rack without modifying the equipment. With an 11.5" shelf depth and standard-width format, it is built for smaller electronics going into shallow racks, wall cabinets, and furniture enclosures. The custom-cut black brushed and anodized face plate finishes the rack opening around your specific component.

Product Description

Control processors, network switches in desktop housings, modulators, headphone amplifiers, and similar half-depth devices rarely come with rack mounting hardware, yet they end up in equipment racks on nearly every project. The RSH4A3S gives that class of gear a proper home: a 3-space (3U) custom rack shelf for standard 19" racks with a shelf depth of 11.5", short enough for shallow wall-mount racks and credenza installations. In the RSH4A model code, 3 denotes the 3U height and S denotes the 11.5" depth; this is the standard-width version for components with conventional chassis proportions. The defining detail of the series is the face plate — black brushed and anodized aluminum, custom cut to the dimensions of the exact component being mounted, so the finished rack space looks like factory rackmount equipment instead of an open shelf. Mounting is completely non-invasive: the component is not drilled, screwed, or permanently attached, which preserves its warranty and makes later replacement painless. The anodized finish matches Middle Atlantic blank panels for a consistent rack elevation from top to bottom. Components with wider chassis at this same shallow depth should use the wide-format RSH4A3SW 11.5" deep wide shelf, while deeper equipment is better matched to the RSH4A3X 17.5" deep custom rack shelf.

Key Features

• Compact 11.5" Shelf Depth — Fits shallow wall racks, furniture enclosures, and equipment closets where full-depth shelves will not.
• Standard-Width 3U Format — Occupies three rack spaces in any standard 19" rack, sized for conventionally proportioned component chassis.
• Custom-Cut Face Plate — Black brushed and anodized plate machined around your specific device for a factory-finished look.
• Non-Invasive Mounting — No drilling or hardware on the component itself, keeping warranties valid and future swaps simple.
• Usable Front Panel — Controls, displays, and IR receivers remain accessible through the custom cutout.
• Matched Rack Finish — Anodized surface blends with Middle Atlantic panels and surrounding rackmount gear.
