The MIDDLE ATLANTIC ERK-RR40 is a rear rail kit designed for 40-space rack enclosures. It provides the rear mounting rail infrastructure required to fully support equipment in open-frame or enclosed rack systems. The kit is sold as a single unit and is intended for installation by AV integrators, IT infrastructure technicians, and low-voltage contractors who need to expand or restore rear rail mounting capacity in an existing rack. The ERK-RR40 is built to fit within the ERK rack family and delivers a direct, hardware-based solution for rear equipment support.
This rear rail kit is suited for 40-space rack configurations used in commercial AV installations, data closets, and equipment rooms. It is typically installed during initial rack buildout or when retrofitting an existing enclosure to accommodate additional rear-mounted equipment. The kit supports organized cable management and proper equipment spacing across all 40 rack units.
Designed as a rear rail accessory for 40-space ERK series rack enclosures. Consult MIDDLE ATLANTIC documentation to confirm fitment with your specific rack model before ordering.
Installation is typically performed by a low-voltage technician or AV integrator during rack assembly or retrofit. Power down and de-rack any equipment in the affected rack sections before installing rear rails. Standard hand tools are sufficient for most rail kit installations. Follow the rack manufacturer's assembly instructions and applicable building codes for equipment room installations.
