Middle Atlantic RSH4A3XX – Custom 3U Rackshelf Enclosure, 20.5" Depth

Product Overview

The Middle Atlantic RSH4A3XX is a custom 3U rackshelf enclosure with the deepest shelf in the RSH4A series at 20.5", built for long-chassis components that have no rack-mount provisions of their own. Its black brushed and anodized face plate is custom-cut at the factory around the specific device you order it for, closing off the 3U opening while keeping the component's front panel fully accessible. It installs in any standard 19" rack or enclosure without modifying the rack or the equipment, and its standard-width opening pairs with the wide-format RSH4A3XXW for broader chassis.

Product Description

Long components are the usual casualties of rack integration: full-depth disc transports, large media servers in consumer housings, and legacy sources often overhang shorter shelves and leave an unfinished gap in the elevation. The Middle Atlantic RSH4A3XX custom rack shelf answers with the XX depth code, 20.5" of usable shelf depth that lets deep chassis sit completely inside the rack with their rear connections reachable.

Decoding the model number: RSH4A identifies the custom rackshelf platform with anodized face plate, the 3 indicates three rack spaces of height, and XX marks the maximum depth tier above the 11.5" S, 14" M, 15.5" R, and 17.5" X options. Choosing 3U rather than 4U recovers a rack space, which matters in shallow credenza and furniture racks where height is scarce.

The anodized black brushed face plate is the visible payoff. Cut to the front-panel profile of the equipment you specify, it presents knobs, displays, and trays through a precise opening and matches the finish of Middle Atlantic enclosures, blanks, and vent panels. Installation is a bolt-in to standard EIA rail holes with no drilling. Because the cutout is machined per order, provide the exact component make and model at purchase. Shipping weight is 8 lb in a 22 x 18 x 2" carton. Build out the rest of the system from the Middle Atlantic collection at Creation Networks.

Key Features

• 20.5" Maximum Depth — The XX depth code is the longest shelf in the RSH4A series, housing full-depth components entirely within the rack.
• 3U Rack Height — Three rack spaces hold substantial gear while using one less unit than the series' 4U shelves.
• Custom Anodized Face Plate — Black brushed and anodized plate machined per order to the exact component you specify.
• Standard 19" Compatibility — Bolts to existing EIA rail holes in any rack or enclosure with no drilling or equipment modification.
• Front-Panel Access — The precision cutout leaves controls, displays, and media slots usable from the front of the rack.
• Series Options — Available in a wide format (RSH4A3XXW) and in shallower depths for shorter components.
