Middle Atlantic - U.s. - Legrand HBL3 3U Blank Panel

Product Description

The MIDDLE ATLANTIC - U.S. - LEGRAND HBL3 is a 3-space anodized blank panel designed to fill unused rack unit openings in standard equipment racks. It provides a clean, finished appearance while blocking open bays that would otherwise allow unmanaged airflow and dust ingress. The anodized finish offers corrosion resistance and a professional look consistent with standard rack installations. This panel is sold as a single unit and is installed by AV integrators, data center technicians, and low-voltage installers working with 19-inch rackmount enclosures.

The HBL3 is suited for use in server rooms, broadcast racks, AV equipment bays, telecom closets, and any application where a 19-inch equipment rack requires blank panel coverage. It occupies 3 rack units of vertical space, making it useful for filling larger gaps between installed equipment. It is appropriate for both new rack builds and retrofit installations where equipment has been removed or reconfigured.

Installation Notes

Installation is performed by low-voltage or AV technicians following standard rack-building practices.

Secure the panel using the appropriate rack screws for the enclosure type, whether cage nut, threading, or tool-less rail. Verify panel alignment with adjacent equipment before final fastening to ensure consistent spacing.
