Roto Patio Inowa’s sealing hardware elevates living spaces with its slim, modern design and components. This hardware for aluminum, vinyl, wood and composite sliding systems supports sash weights up to 882 pounds and dimensions up to 9.8 feet wide and 11.8 feet high. The Roto Patio Inowa operates with ease due to its innovative closing movement and soft close and soft open functions, which protect the sliding element by mechanically braking the sash to prevent it from slamming against the frame. Highly customizable and tested to the highest quality standards, the tightly sealed system provides sound insulation, burglar inhibition and harsh weather deterrence.
