Middle Atlantic SR28-RR40 Rack Rail Kit 40 Space

Product Description

The MIDDLE ATLANTIC SR28-RR40 is a rack rail kit designed for mounting equipment in 40-space, 28-inch-wide rack enclosures. The kit provides the mounting rails necessary to install and secure standard EIA-310-compliant rack equipment within compatible SR-series open-frame or enclosed rack systems. It is used by AV installers, IT infrastructure technicians, and low-voltage contractors who need reliable rail hardware when building out or retrofitting equipment racks. The SR28-RR40 ships as a single kit unit and is suited for both new rack builds and field replacements where original rails need to be swapped out.

This rail kit is intended for 40-space rack installations requiring a 28-inch internal width. It fits residential and commercial AV, network, and data distribution builds where SR-series rack frames are already deployed. Installers working on equipment rooms, server closets, home automation enclosures, and structured wiring bays will find this kit applicable. The kit is sold as a single unit and is intended to restore or complete a rack frame rather than serve as a standalone structure.

Key Features

• 40-space rack height accommodates a high density of rack-mount equipment
• 28-inch internal width matches SR-series rack frame dimensions
• Designed for use with MIDDLE ATLANTIC SR-series rack systems
• Sold as a complete rail kit (quantity: 1 kit per unit)

Compatibility

Designed as an OEM-style replacement or supplemental rail kit for MIDDLE ATLANTIC SR-series rack enclosures with a 28-inch width and 40-space height configuration.

Installation Notes

Installation is typically performed by low-voltage technicians or AV systems integrators. Power down and de-rack all equipment before removing or installing rack rails to prevent damage to mounted gear. Standard hand tools including a screwdriver and cage-nut setter are commonly used. Follow local building and low-voltage codes as applicable to the installation environment.
