Offset ceiling plate for heavy projectors

The CHIEF CMA330 is a projector ceiling plate rated for 500 lbs (226.8 kg). It suits installers mounting large-venue projectors where structural capacity is critical. The 1.5" NPT threaded connection fits standard extension columns used in commercial AV infrastructure.

8-inch square plate with 1.75-inch offset

The 203 mm square plate provides a broad mounting footprint for stability. A 44 mm high offset creates a cable exit path when attaching to a flat ceiling surface. Overall height measures 114 mm, keeping the projector close to the ceiling while allowing wires to route through the column and out the top.

Cable routing through extension column

The offset design lets projector cables pass internally through the extension column and exit above the ceiling plate. This conceals wiring for a clean installation and protects cables from damage. No additional accessories or software are included with the plate.
