The Yard Master Retractable Series features an option of manual or electric projector screens bringing home theater quality to the outdoors. The series is IP33 certified for rain/water protection using an enameled weather-resistant aluminum casing meant to accessorize a backyard or patio — or anywhere a gathering for evening movie time is appropriate. The components are made from rustproof materials including the housing, roller tube, brackets, handle, weight bar, and floating wall/ceiling brackets. The floating brackets are meant to provide the installer with a perfectly centered installation, every time, said Elite. The product arrives fully assembled and ready to install. The Manual variants feature a Slow Retract Mechanism (SRM). This utilizes a hydraulic arrester that allows the screen to rise back into its housing unassisted.
