Middle Atlantic BL4 4U RMS Flanged Aluminum Rack Blank Panel

Keep server, security and AV racks looking professional while protecting critical equipment with the Middle Atlantic by Legrand BL4 4U flanged aluminum rack blank panel. Engineered as a finishing element for networking, monitoring and surveillance cabinets, this flange panel provides a sleek black brushed anodized finish that complements Middle Atlantic shelves and accessories. Constructed from durable 16-gauge aluminum, the BL4 slows dust entry and offers easy machinability so integrators can create cable pass-throughs or custom cutouts on-site. The 4RU flanged profile secures firmly to standard rack rails for a smooth, low-profile face that improves airflow management and makes maintenance tasks faster. Ideal for security control rooms, CCTV and NVR enclosures, or communications closets, the BL4 helps maintain tidy cable routing and a polished system appearance. Backed by a limited lifetime warranty, it’s a practical choice for long-term installations.
