The CMA-101W Ceiling Plate (White) from Chief is a ceiling plate designed to serve as the main support in a ceiling-mounted installation. It features four holes for mounting and can be affixed using either two opposing holes or all four openings. Its 4 x 4" mounting pattern is designed for use with 3/8" mounting bolts.
This plate features a threaded fitting that accepts a 1.5" NPT threaded extension, allowing you to build out your custom system using a pole-style installation that hangs from your ceiling. All assembly hardware is included.
