Middle Atlantic RSH4S3R Custom Rack Shelf 3 Space

Product Description

The MIDDLE ATLANTIC - U.S. - LEGRAND RSH4S3R is a custom rack shelf designed for equipment mounting in professional rack enclosures. Spanning 3 rack spaces, this shelf provides a stable, horizontal mounting surface for audio, video, data, or control equipment commonly installed in equipment racks across commercial and residential AV, IT, and facility management applications. At 15.5 inches in usable depth, it accommodates a range of rack-mountable components and accessories. This shelf is typically installed by AV integrators, low-voltage technicians, and IT infrastructure professionals working with standard 19-inch rack systems.

This shelf is suited for use in standard 19-inch rack enclosures in commercial buildings, server rooms, control rooms, and structured wiring installations. It supports the organization and secure mounting of equipment across 3 rack units of vertical space. Applications include AV distribution gear, network switches, control processors, and other rack-mounted hardware that requires a solid shelf surface rather than direct rail mounting.
