Middle Atlantic RFB119-SKO 1-Gang 1/2 In. and 3/4 In. Knockout Panel
Overview
The Middle Atlantic RFB119-SKO is a 1-gang rack panel with pre-scored 1/2 in. and 3/4 in. knockouts, designed to provide controlled cable entry and exit points in rack enclosure builds. When you need to route conduit, flexible cable runs, or pass-through cabling into a rack without leaving open slots that compromise airflow management or create a security gap, this panel gives you the right punch-out sizes in a single 1U-equivalent space. It replaces improvised solutions — a proper knockout panel keeps your build clean, maintains chassis integrity, and takes minutes to install.
Compatibility
Designed for use with Middle Atlantic rack enclosures and rack enclosure accessory systems that accept standard 1-gang panel blanks. Compatible with the Middle Atlantic RFB (Rack Frame Bracket) series and any Middle Atlantic rack or enclosure that uses 1-gang accessory panel slots. Verify your enclosure's gang slot dimensions before ordering — this panel is sized for the 1-gang opening standard across the Middle Atlantic RFB line.
Installation Notes
Knock out only the sizes you need — unused knockouts remain intact to preserve panel rigidity and limit unnecessary cable routing paths. Use a standard punch-out tool or pliers to remove knockouts cleanly. Once a knockout is removed it cannot be replaced, so plan your cable routing before committing. Pair with appropriate cable management hardware and grommets or bushings to protect cable jackets at the panel edge and maintain a professional finish.
