Middle Atlantic ABPLUG10 10-Inch Rack Abandonment Plug

Overview

The Middle Atlantic ABPLUG10 is a 10-inch abandonment plug designed to seal unused or decommissioned cable entry points in rack enclosures and wall-box systems. When a cable run is removed or rerouted, the resulting open penetration compromises fire and airflow integrity — the ABPLUG10 caps that opening cleanly without requiring a full panel replacement. This is the part to specify during rack decommissioning, system upgrades, or any retrofit where a previously used knockout or grommet opening needs to be closed out permanently or semi-permanently.

Compatibility

The ABPLUG10 is designed for use with Middle Atlantic rack enclosures and cable management systems that accommodate 10-inch penetration openings. It is suited for installation in Middle Atlantic BGR, BGRT, and similar bolt-together rack families as well as wall-mount enclosures that share the same knockout footprint. Confirm the exact opening diameter of your enclosure before ordering — Middle Atlantic offers abandonment plugs in multiple sizes, and the 10-inch designation refers to the plug's fit dimension. If your enclosure uses a different knockout size, verify against the Middle Atlantic rack accessories lineup for the correct variant.

Installation Notes

Installation is a tool-free or minimal-tool press-fit depending on the specific enclosure generation. Ensure the target opening is clear of existing grommets or gland plates before seating the plug. The plug should sit flush with the panel surface to maintain the enclosure's intended airflow and cable management geometry. Do not force the plug into an undersized opening — mismatched sizes risk cracking the plug body or leaving gaps that defeat the purpose of the seal.
