Middle Atlantic CRFB-KO-4 Device Plate

Overview

The CRFB-KO-4 is a knock-out device plate designed for use with Middle Atlantic CRFB series rack frames. It fills unused rack openings in CRFB enclosures, keeping interiors organized and maintaining proper airflow management across installed equipment. If you're building out a CRFB-series rack and need to blank or adapt an open bay, this plate is the purpose-built fit — generic blanks won't align correctly to CRFB frame geometry.

Compatibility

The CRFB-KO-4 is engineered for Middle Atlantic CRFB series rack frames. It is intended for installations using the CRFB enclosure line where device plate knock-outs are required to accommodate custom cable routing or module cutouts. Confirm your specific CRFB frame model against Middle Atlantic's current CRFB accessory compatibility matrix before ordering, as CRFB frame variants may have differing plate requirements.
