The MIDDLE ATLANTIC - U.S. - LEGRAND ERK-40-R-EXT3 is a 40U three-section rear door extension designed specifically for ERK series open-frame racks. This accessory mounts to the rear of a compatible ERK rack to extend door coverage across the full 40U height of the enclosure. It provides additional depth clearance and structured cable management support at the rear of the rack, making it a practical addition during rack builds or retrofits in data, AV, or network equipment installations. Installation is performed by systems integrators, low-voltage technicians, or AV rack builders working in structured wiring environments.
This rear door extension is suited for commercial and enterprise environments where ERK series racks are deployed in equipment rooms, server closets, telecom rooms, or AV headend racks. It is designed to accommodate the standard ERK rack footprint and is sold as a single unit. The three-section construction allows the extension to align with the rack's rear vertical mounting rails while maintaining access to installed equipment.
Designed as a rear door extension accessory for ERK series 40U open-frame racks from Middle Atlantic.
Installation is typically performed by low-voltage technicians or AV systems integrators. Power down and de-energize all active equipment in the rack before beginning any structural rack work. Follow the rack manufacturer's mounting instructions and ensure all fasteners are fully seated before resuming equipment operation. Local codes for structured cabling and equipment rooms may apply.
