Middle Atlantic R4CN-5136B R4 Series 4-Post Open Frame Rack, 36" Deep, 51U RMS, Black

Designed to centralize and protect mission-critical networking, AV and surveillance equipment, the Middle Atlantic by Legrand R4CN-5136B R4 Series 4-post open frame rack delivers a reliable infrastructure backbone for security, monitoring and enterprise IT deployments. This 51U RMS rack with 36" deep mounting depth accommodates deeper, heavier components—like switches, routers, VoIP systems and NVRs—while the open-frame 19" rack width preserves unobstructed airflow to reduce thermal risk. Installers benefit from flexible mounting options including inward or outward base mounts, a split rackrail for multiple mounting depths, and gangable ports to expand capacity across rooms or closets. Built from heavy-gauge steel and aluminum, TAA and UL listed, and backed by a lifetime limited warranty, the R4CN-5136B meets compliance needs for government and commercial projects. Its thoughtful design minimizes setup time and simplifies cable ladder attachment to streamline surveillance, security and data center builds.
