Middle Atlantic RSH4A3SW – Custom 3U Wide Rackshelf Enclosure, 11.5" Deep

Product Overview

The Middle Atlantic RSH4A3SW is a shallow, wide-format custom 3U rack shelf enclosure for mounting non-rackmount AV components in standard 19" racks. Its 11.5" shelf depth is the shortest in the 3U RSH4A lineup, making it the right pick for wall-mount racks, credenza enclosures, and other depth-constrained installations. A black brushed and anodized face plate, custom cut around your component, closes off the rack opening for a clean finished result.

Product Description

Depth is the limiting factor in a large share of AV rack installations — wall racks behind displays, furniture-integrated enclosures, and shallow equipment closets all rule out full-depth shelving. The RSH4A3SW pairs a compact 11.5" shallow rack shelf with the wide-format face plate option, so broader low-profile components such as compact mixers, wireless receivers in wide chassis, or media players still mount cleanly where rack depth is tight. The model code breaks down simply: 3 for the 3U rack height, S for the 11.5" depth, and W for the wide format. Like every shelf in the RSH4A series, the black brushed and anodized face plate is custom cut to the dimensions of the specific component being mounted, producing a rack elevation that looks engineered rather than improvised. The component sits on the shelf untouched — no drilling, no chassis hardware — so the manufacturer warranty stays intact and the device can be swapped out later without leaving holes in anything. Front-panel controls and indicators remain visible through the cutout, which matters for gear that gets adjusted or monitored during normal operation. If the component fits a conventional chassis width, the standard-width RSH4A3S 11.5" deep custom shelf covers the same shallow footprint. Installations with more available depth can step up to the RSH4A3RW 15.5" deep wide rack shelf for larger equipment.

Key Features

• Shallow 11.5" Depth — The shortest 3U shelf in the RSH4A series, sized for wall-mount racks, credenzas, and depth-limited enclosures.
• Wide-Format Face Plate — Accommodates broader component chassis than the standard-width version while keeping the same shallow footprint.
• Custom-Cut Anodized Plate — Black brushed and anodized face plate machined around your specific component for a finished appearance.
• 3U Standard Rack Fit — Mounts in three rack spaces of any standard 19" rack or enclosure without modification to the rack or equipment.
• Warranty-Safe Mounting — The component is never drilled or altered, preserving manufacturer coverage and resale condition.
• Operational Access — Front controls, displays, and IR windows stay usable through the custom cutout.
