About this detail

An overhead support and housing installation for a motorized projection screen is mounted above a finished ceiling. The screen housing is suspended from the concrete structure using three-eighths-inch all-thread rods equipped with one-and-five-eighths-inch channel stiffeners for vertical hangers sixteen inches or longer, supplemented by twelve-gauge wire braces with four tight turns and metal couplers for lateral stability in both directions. The housing features a hinged access door along its full length for servicing the screen and motor assembly, allowing the projection screen to drop through a trap door into its operating position. Electrical connections include a junction box wired to the screen motor and a low-voltage control wall switch.
