Blank Panel for 3 RU Server Racks

The Middle Atlantic BL3 is a blanking panel built from 16-gauge aluminum with a flanged edge. It presents a black brushed and anodized finish that resists wear in equipment rooms. The panel fills unused rack openings to manage airflow and maintain a tidy appearance. Its construction allows straightforward machining when custom cutouts are required.

Installers Needing Airflow Control and a Clean Look

This panel suits technicians who must seal empty rack spaces in a 3 RU increment. It helps direct cooling air through active equipment rather than bypassing through gaps. Buyers who need a vented or louvered panel for passive heat dissipation should look at a different design. Anyone requiring a solid metal filler without a flanged mounting style will not match this part.

16-Gauge Aluminum Flanged Construction

The defining specification is the 16-gauge aluminum sheet formed with a flanged edge. This thickness provides rigidity while remaining easy to drill or cut on site. The black brushed and anodized surface is integral to the panel, not a separate coating. Confirm that your rack accepts flanged blank panels before ordering.

Questions about this item

What comes in the box and is any mounting hardware included?

The package contains the blank panel itself; mounting screws are not supplied and must be purchased separately.

How do I decide between the different rack-unit sizes in the BL range?

This model occupies 3 rack units (5-1/4 in.) — choose it when you need to cover a 3-space opening in the rack.

What does the 16-gauge aluminum construction mean for everyday use?

The 16-gauge aluminum is rigid enough to stay flat when bolted in place yet soft enough to drill or cut for custom cable entries.
