sliding patio door hardware

Roto introduces its Roto Patio Alversa and Roto Patio Inowa (pictured) series sliding patio door hardware. The Alversa has one tilt and slide solution and three parallel sliding solutions and has a universal central locking system, night ventilation function, and ball-bearing-mounted roller unit with integrated anti-jemmy protection. Inowa is positioned as smart hardware thanks to its closing movement of the sash transverse to the frame profile, surrounding gasket and active locking points in the mullion. The SoftClose function will be available Summer 2020.
