Middle Atlantic PROWRK-RR40 40U Rack Rail Pair

Product Description

The MIDDLE ATLANTIC - U.S. - LEGRAND PROWRK-RR40 is a pair of 40-space rack rails designed for use with the Proliant Workhorse rack enclosure series. These rails provide the structural mounting interface for rack-mount equipment, accepting standard 19-inch rack unit components. Installers use these rails to outfit or replace the mounting points inside compatible Proliant Workhorse frames, ensuring equipment is seated and secured at the correct rack unit positions. The PROWRK-RR40 ships as a matched pair, covering both the left and right sides of the rack.

This rail pair is suited for AV system integrators, IT infrastructure technicians, and facility installers working with Proliant Workhorse rack enclosures. Typical applications include new rack builds, rail replacement due to wear or damage, and retrofit installs where additional mounting capacity is needed within an existing enclosure. At 40 spaces, these rails accommodate high-density equipment loads in both commercial and institutional environments.
