Middle Atlantic EFB10-S2 10U EVO Recessed Filler Blank Panel

Overview

The Middle Atlantic EFB10-S2 is a 10U recessed filler blank plate designed for the EVO rack enclosure series. It fills unused rack space in EVO frames to maintain airflow integrity, prevent cable ingress, and keep the installation looking finished — a small detail that matters in client-facing AV racks and secure equipment rooms alike. Without a filler panel in open rack space, convective airflow short-circuits across the front face instead of moving through equipment, which raises operating temperatures in adjacent gear. The EFB10-S2 closes that gap at 10U. The recessed profile sits flush or slightly inset relative to the rack plane, keeping the front face clean rather than creating a protruding panel that interferes with rack doors or cable management.

Compatibility

The EFB10-S2 is designed for Middle Atlantic EVO series rack enclosures and open-frame racks that follow the EVO rail geometry. The EVO product family covers Middle Atlantic's current-generation two-post and four-post rack frames used widely in rack enclosure deployments for security, AV, and IT infrastructure. If you are specifying a full EVO build — including rack accessories such as shelves, drawers, ventilation, and power distribution — verify that the filler blank variant matches your rail spacing and rack depth before ordering.
