Product Overview
The Middle Atlantic ERK-2120LRD is a 21-space, 20-inch deep stand-alone open rack enclosure without a rear door. It provides a compact, accessible equipment rack solution for AV and IT deployments where rear access is not restricted and a fully enclosed rear panel is not required.
Product Description
Not every rack deployment requires a full enclosure. The ERK-2120LRD is configured without a rear door, providing full open rear access to cables, patch panels, and equipment rear connections at all times. At 21 rack spaces and 20 inches deep, this enclosure is well-suited to compact deployments and spaces where depth is constrained. The ERK series is a foundational Middle Atlantic rack product widely used across AV integration and IT infrastructure projects.
