Middle Atlantic AL5256-MABRT RT Series MAB Cover Plate

Overview

The AL5256-MABRT is a cover plate designed for Middle Atlantic RT Series rack enclosures configured with MAB (Mounting Accessory Base) panels. Cover plates serve a specific functional role in rack builds: they close unused panel openings, maintain consistent airflow paths, and deliver a finished appearance in client-facing AV and security equipment rooms. Without proper blanking, open rack slots disrupt front-to-back airflow and create entry points for dust — both factors that shorten equipment life in 24/7 security and AV installations.

Compatibility

The AL5256-MABRT is engineered for use with Middle Atlantic RT Series rack enclosures paired with MAB-style panel configurations. Verify your specific RT Series enclosure model and MAB panel variant against Middle Atlantic's current rack accessory compatibility matrix before ordering — RT Series enclosures span multiple width and depth configurations, and cover plate fitment is frame- and panel-specific. This plate is not a universal rack blank and is not designed for use with Middle Atlantic's BGR, BGR-AR, or WM Series enclosures, or with third-party rack frames.
