Middle Atlantic 432BR Triple Blanking Plate

Overview

The Middle Atlantic 432BR is a triple-unit blanking plate finished in brass, designed to cover unused rack openings in AV and equipment enclosure installations. Where rack bays go partially populated — common in phased deployments or mixed-use enclosures — open slots compromise airflow management and introduce dust ingress. The 432BR fills three rack units of unused space cleanly, maintaining proper thermal pathways and a finished appearance. TAA-compliant, making it a straightforward procurement choice for government and federally funded projects.

Compatibility

Designed for use with Middle Atlantic rack enclosures and open-frame rack systems that follow standard EIA-310 rack unit spacing. The brass finish aligns with Middle Atlantic's brass-hardware accessory line, making it appropriate for installations where finish consistency across rack furniture matters — AV control rooms, boardrooms, and facilities where equipment presentation is part of the spec. Verify rack unit count against your enclosure before ordering: this plate occupies three contiguous rack units (3U).
