Middle Atlantic BL1 Flanged Aluminum Anodized Black | Rack Accessory

Fill unused rack space with a simple, durable finishing component that improves both appearance and enclosure discipline. The Middle Atlantic BL1 is a 1-space flanged aluminum panel finished in anodized black, making it a practical choice for closing open rack units in professional installations. In a well-built rack, blank space is not just visual noise. It can affect how cleanly the system presents, how easily the front of the rack is managed, and how consistent the overall installation feels. A flanged panel gives the opening a more finished edge than a basic filler, which is why it is often specified in higher-end AV and IT builds. This type of accessory is especially useful when the rack is visible to clients, staff, or operators. The anodized black finish blends with common rack hardware and helps maintain a uniform front plane across the enclosure. For integrators, it is a small part with an outsized effect on the final result.
