Middle Atlantic WRK-RR40 – 40 RU Rack Rail Kit for WRK Series

Product Overview

The Middle Atlantic WRK-RR40 is an additional 40-space rack rail kit for WRK Series enclosures, supplied as a matched pair of heavy-gauge steel rails. Each rail is threaded 10-32 along all 40 rack units, giving integrators a second mounting plane for rear support of deep equipment or added accessory capacity. A protective e-coat finish guards the steel against corrosion through transport, staging, and long service in equipment rooms. It is a straightforward way to expand mounting options in an existing WRK rack without modifying the enclosure.

Product Description

WRK Series racks ship with a single pair of rack rails, which is sufficient for shallow gear but leaves heavier amplifiers, servers, and UPS units supported only at the front. Adding the WRK-RR40 rack rail kit creates a rear mounting plane so four-point rack shelves, rail-to-rail supports, and deep chassis can be secured properly. The heavy-gauge steel construction holds threads under repeated installs, a practical concern on rental, staging, and frequently reconfigured systems. Tapped 10-32 threading across all 40 rack spaces means no cage nuts to load and no skipped positions, which speeds rack assembly during system builds. The protective e-coating resists scratching and corrosion, keeping the rails serviceable in equipment closets, data rooms, and venue installations. Because the kit is sold as a pair, one part number covers a complete rear rail upgrade for a 40 RU WRK enclosure. Integrators can also use the kit to replace damaged rails or standardize rail configurations across multiple racks on a project. Pair it with vented shelves, lacing bars, and power accessories from our Middle Atlantic collection to complete the build.
