Middle Atlantic RSH4A3X – Custom 3U Rackshelf Enclosure, 17.5" Deep

Product Overview

The Middle Atlantic RSH4A3X is a custom 3U rackmount shelf enclosure built to put a non-rackmount AV component into a standard 19" rack with no modification to the equipment. The 17.5" shelf depth supports full-depth chassis end to end, while the black brushed and anodized face plate is custom cut to frame your specific component. For integrators, it turns a loose set-top device or hi-fi component into a finished rack space that matches the rest of the elevation.

Product Description

Plenty of AV equipment worth racking — streaming transports, cable boxes, hi-fi separates, conferencing codecs — ships without rack ears or any mounting provision. The RSH4A3X addresses this with a 3-space custom rack shelf enclosure for standard 19" racks: the component sits on the shelf, and a precision-cut anodized face plate closes off the rack opening around it. Decoding the model number, 3 indicates the 3U height and X indicates the 17.5" depth, which is the longest standard shelf in the 3U lineup and supports deep electronics across their full footprint rather than leaving the rear of the chassis cantilevered. This is the standard-width version, suited to components with conventional chassis widths; equipment with an unusually broad chassis should go on the wide-format RSH4A3XW wide rack shelf instead. The black brushed and anodized finish presents the same appearance as Middle Atlantic blank panels and faceplates, so the mounted component reads as native rackmount gear in the finished rack. Nothing about the installation alters the component — no drilling, adhesives, or chassis screws — which protects warranties and simplifies replacement when the equipment is eventually upgraded. Front-panel controls, displays, and IR windows stay visible and usable through the custom cutout. For shallow wall racks and credenza enclosures where 17.5" will not fit, the RSH4A3S 11.5" deep rack shelf offers the same 3U custom-cut treatment in a shorter footprint.

Key Features

• 3U Custom Shelf Enclosure — Converts three rack spaces in a standard 19" rack into a finished mounting bay for a non-rackmount component.
• 17.5" Shelf Depth — The longest standard depth in the 3U RSH4A group, supporting deep AV chassis across the full footprint.
• Precision-Cut Anodized Face Plate — Black brushed and anodized plate is cut around your specific component for an integrated, factory look.
• Zero Equipment Modification — No drilling or hardware attached to the component, keeping the manufacturer warranty intact.
• Front-Panel Access Preserved — Controls, displays, and IR receivers remain visible and reachable through the custom cutout.
• Consistent Rack Aesthetics — Finish matches Middle Atlantic panels so mixed equipment racks keep a uniform appearance.
