Ceiling opening trim kit is designed for ceiling-recessed installation of Targa and Premier electric projection screens. Assembles quickly with fasteners provided. The kit attaches to the screen end caps and forms a finished slot in the ceiling allowing for passage of the projection screen surface. Painted white to match the ceiling. Slot includes finished flange to accept acoustical ceiling tile or grid. Slot measures 54mm in depth. Once installed the finished slot length is equal to the Targa or Premier screen case length. Can also be used on the manual Luma 2 screen. Not recommended for the Luma 2 with AR.
