Middle Atlantic Single Gang Cover 1IN KO - SGT-1KO

Middle Atlantic SGT-1KO Single-Gang Wall Plate Cover with 1-Inch Knockout

Overview

The Middle Atlantic SGT-1KO is a single-gang wall plate cover with a 1-inch (25mm) knockout, designed to finish wall openings at AV termination points and low-voltage infrastructure runs. In retrofit and new-construction installs alike, open single-gang mud rings or rough-in boxes left uncovered are a code concern and a visual liability — the SGT-1KO closes that out with a clean, professional face. It fits the standard single-gang wall box footprint and delivers a finished look at cable entry points for security, AV, and structured cabling runs. The 1-inch knockout accommodates common conduit connectors and grommeted cable pass-throughs without modification.

Compatibility

The SGT-1KO mounts over any standard single-gang electrical box or mud ring, making it compatible with the broad range of Middle Atlantic rack and in-wall infrastructure systems that terminate at single-gang wall positions. It is appropriate for wall plate and cover applications in AV distribution, structured cabling, and security system accessories where a 1-inch knockout is the required cable egress. Works with standard single-gang boxes used in commercial drywall, masonry, and modular partition installations. The 25mm knockout size suits typical low-voltage conduit connectors and snap-in cable grommets used in most commercial AV and security infrastructure deployments. For runs requiring larger conduit penetrations or multi-gang coverage, a different plate size or knockout dimension will be needed — verify your conduit connector OD before ordering.

Installation Notes

Mounts directly to any standard single-gang box using the box's existing screw pattern — no special hardware required. Knock out the 1-inch slug before or after mounting depending on access constraints. Ensure the wall box is flush-mounted or set to the correct depth for the wall finish; a recessed box will leave a visible gap around the plate perimeter. For low-voltage cabling installations, use a snap-in grommet in the knockout to protect cable jacket from the knockout edge.
