Middle Atlantic ERK-44-R-EXT3 Rack Rear Extension 44SP

Product Description

The MIDDLE ATLANTIC - U.S. - LEGRAND ERK-44-R-EXT3 is a rear extension kit designed for 44-space equipment racks, adding 3 inches of additional depth to the rear of an existing rack enclosure. This accessory allows installers to accommodate deeper equipment, additional cable management hardware, or supplemental mounting rails without replacing the existing rack frame. It is used primarily in structured wiring, AV integration, data, and low-voltage electrical installations where rack depth must be extended to fit modern equipment profiles.

This rear extension kit is suited for commercial and residential rack installations where standard rack depth is insufficient for the equipment being deployed. Typical applications include server rooms, AV equipment closets, network infrastructure enclosures, and low-voltage utility spaces. It is installed by AV integrators, low-voltage technicians, and structured wiring professionals working with 44-space open-frame or enclosed rack systems.

Follow applicable low-voltage installation codes and the rack manufacturer guidelines for load ratings when adding depth extensions.
