The DA-LITE 94286LS Advantage® ceiling recessed electric screen series is designed with ceiling trim in place, to conceal the rough opening eliminating the need to complete additional trim work once the screen is installed. Its two-stage installation option affords the screen case to be installed during the rough-in construction stage, and the screen surface assembly during the finishing stage. Sliding installation brackets allow mounting flexibility for easy attachment of the screen housing to the structure above the drop ceiling.
