Middle Atlantic RSH4A4R – Custom 4U Rackshelf Enclosure, 15.5" Depth

Product Overview

The Middle Atlantic RSH4A4R is a custom 4U rackshelf enclosure that lets integrators mount virtually any non-rackmount component in a standard 19" rack or enclosure without modification. Part of the RSH4A series, it pairs a 15.5" deep shelf body with a black brushed and anodized face plate that is custom-cut for the specific equipment you are racking. The result is a clean, factory-finished front panel around gear that was never designed for rack mounting. At 4U (four rack spaces), it handles taller source components, small mixers, and media players that will not fit a lower-profile shelf.

Product Description

Every AV rack build eventually runs into a component with no rack ears: a streaming media player, a residential-grade source, a compact DSP, or a desktop-format processor. The Middle Atlantic RSH4A4R custom rack shelf solves this by combining a rigid 4U shelf with an anodized face plate machined to match the exact faceplate profile of the device you specify at order time. The cutout frames the component's front panel so controls, displays, and disc trays stay accessible while the rack retains a uniform, professional appearance.

The "R" depth code in the RSH4A4R designates a 15.5" shelf depth, sitting between the 14" (M) and 17.5" (X) versions in the series. That extra depth gives chassis-style components and their rear cabling room to land inside the rack without crowding rear rails or power strips. The black brushed and anodized finish matches Middle Atlantic rack enclosures and blank panels, so the shelf disappears into the elevation rather than standing out.

Installation follows standard EIA practice: the shelf bolts into any 19" rack or enclosure using the existing rail holes, with no drilling or chassis modification required. Because the face plate is custom-cut per order, confirm the make and model of the component being mounted when ordering. The unit ships at 8.05 lb in a 21.575 x 17.874 x 2.126" carton.

Key Features

• Custom-Cut Face Plate — The black brushed and anodized 4U face plate is machined for the specific non-rackmount component you specify, framing its front panel cleanly.
• 4U Rack Height — Four rack spaces of vertical capacity accommodate taller consumer and pro-AV components that exceed 1U or 2U shelf limits.
• 15.5" Shelf Depth — The R-series depth supports deeper chassis components while leaving room for rear cable dress inside the rack.
• No-Modification Mounting — Installs in any standard 19" rack or enclosure using existing rail holes; the mounted component requires no drilling or alteration.
• Finish-Matched Aesthetics — The anodized black brushed finish blends with Middle Atlantic racks, blank panels, and vent panels for a uniform equipment elevation.
• Front-Panel Access Preserved — The custom cutout keeps the device's controls, indicators, and media slots usable from the front of the rack.
