Middle Atlantic RSH4S3XW – Custom 3U Wide Rack Shelf, 17.5" Depth

Product Overview

The Middle Atlantic RSH4S3XW is a wide-format custom 3U rack shelf with a textured black powder-coat steel face plate, cut at the factory to fit the specific component you intend to mount. The 17.5-inch shelf depth pairs extended chassis support with the wide body of the RSH4S W series, making it the choice for larger consumer-grade electronics that exceed the standard shelf opening. It drops into any standard 19-inch rack or enclosure, and the component itself requires no drilling, brackets, or modification. The finished installation reads as purpose-built rackmount equipment.

Product Description

Oversized consumer components are a recurring headache in rack integration: too wide for a standard custom shelf, too valuable to leave on a side table. The RSH4S3XW addresses this with a wide-body shelf platform and a face plate that Middle Atlantic custom cuts to your component's exact front-panel profile. The company's measurement database covers more than 8,000 devices, so the cutout arrives sized correctly the first time, with a snug fit and no gaps around the chassis.

At 17.5 inches deep, this shelf carries longer wide-format gear that would overhang the shallower W-series models. Included rear brackets stop the component from creeping backward out of the enclosure, and the ventilated bottom panel allows convective airflow beneath the chassis — useful in closed AV cabinets where heat accumulates. The textured black powder-coat steel matches the rest of a Middle Atlantic rack elevation, including blanks, vents, and panels. Specify the make and model of your equipment at the time of order; if you are unsure whether your component calls for the wide version, Creation Networks can verify dimensions against the Middle Atlantic database before you commit.
