Overview
Built for reliability in security, surveillance and enterprise AV applications, the Middle Atlantic by Legrand ERK-2120LRD is a 21U rack frame engineered to protect and organize critical equipment. The 20" depth accommodates a wide range of servers, switches and DVR/NVR appliances while a 2,500 lb weight capacity and seismic certification (when installed with ERK-Z4 brackets) deliver confidence in demanding installations. Fully welded steel construction and numbered, adjustable 10-32 rack rails speed installation and simplify moves, adds and changes. Vented top and bottom panels plus integrated lacing points and slotted rail brackets provide superior cable management and thermal performance—helping reduce heat-related failures in monitoring and networking racks. The ERK series also gangs to form partitioned multi-bay enclosures, enabling secure, efficient deployments in control rooms and surveillance closets. UL listed and TAA compliant, this black wrinkle powder-coated frame is an ideal backbone for AV, IT, security and monitoring systems. Specify the ERK-2120LRD for your next project to streamline installation and protect critical infrastructure—order or contact sales for deployment guidance.
