Middle Atlantic 829CKAL-1NK Rectangular Feed Plate with 1-In Screw Plug, Nickel
Overview
The Middle Atlantic 829CKAL-1NK is a rectangular communications cover plate finished in nickel, designed for concrete floor box installations where a clean, furniture-grade surface termination is required. The 1-inch screw plug allows a single cable or conduit pass-through while keeping unused openings sealed — useful in open-plan office, conference room, or commercial AV/security installations where the floor box sits exposed in a finished space. TAA compliance makes it eligible for federal, government, and GSA-schedule projects without additional sourcing review. The 829CKAL-1NK ships at 8.5" x 0.5" x 22.25", so verify your rough-in opening dimensions before ordering.
Compatibility
Designed for the Middle Atlantic 829CKAL series concrete floor boxes — specifically the 829CKAL-1BS communications cover plate family. Confirm your floor box model accepts a rectangular feed plate insert before ordering; round or modular-format boxes in the Middle Atlantic line use different cover plate profiles. The nickel finish coordinates with standard brushed-nickel architectural hardware common in commercial interiors.
Installation Notes
The 0.5-inch profile depth is shallow — confirm your floor box cover recess accommodates this plate flush with the finished floor surface. The screw plug seats into the 1-inch knockout; remove only if routing cable through that port, and retain the plug if the opening is unused to maintain a clean finished appearance and reduce debris ingress into the box. No special tooling is specified beyond standard installation hardware for the 829CKAL box series.
