Middle Atlantic CRD-WMRK-42LH CRD Series Split Solid Rear Door for WMRK Racks with Handle Knockout, 42U

Protect critical IT, networking and surveillance equipment with the Middle Atlantic CRD Series split solid rear door—designed to deliver secure, service-friendly rear access for WMRK rack installations. This CRD-WMRK-42LH rear door accepts standard handle hardware via a knockout, enabling simple lock or handle installation to meet access-control and compliance requirements. As a 42U split solid rear door engineered for WMRK racks, it helps isolate equipment from unauthorized access while reducing dust and light intrusion that can affect sensitive monitoring and security gear.

Built for integrators and IT managers, the CRD Series door balances physical security with practical serviceability: the split design lets technicians access upper or lower sections without removing the entire panel, and its durable construction supports long-term use in data centers, security rooms, and network closets. Use it to enhance rack-level security for surveillance servers, access-control hardware, and networking equipment while maintaining tidy cable routing and airflow. Specify the CRD-WMRK-42LH for your next rack deployment to improve equipment protection and streamline maintenance.
