Chief CMA-106 Junction Box Assembly Ceiling Plate

The Chief CMA106 is a ceiling plate that allows you to anchor a projector mount directly to a standard junction box and span the space between ceiling joists. It accepts any length of 1.5-inch NPT pipe, so you can set the projector at the exact height your room requires. Once installed, it provides a dependable mounting point rated for up to 50 lbs (22.7 kg), which covers most classroom, office, and home theater projectors.

Installers appreciate the straightforward process: align the 102 × 102 mm pattern with the junction box, secure the plate, thread in a fixed or adjustable extension column, and you are ready to attach the projector mount. Because the plate works with both fixed and adjustable columns, it fits equally well in rooms with low ceilings and in venues that need a longer drop, such as auditoriums or training centers.

For integrators who manage multiple projects, using a common NPT standard simplifies inventory and keeps future upgrades easy. Home theater enthusiasts benefit from the clean look the ceiling plate creates by routing the projector cabling through the pipe and out of sight. Whether you are outfitting a single conference room or an entire campus, the CMA106 delivers a stable, professional foundation for a clear, well-aligned image.
