MB-79N CASEMENT OPERATOR is the first thermally insulated aluminium window system with a crank-out mechanism designed for the US market, available to manufacturers in Poland. It combines comfort of use, modern appearance and high functionality – in line with the requirements of the American market. The window opening mechanism located on the bottom edge is easily accessible even for people with mobility issues. The system allows for the use of a frame mosquito net, which makes these structures not only convenient but also practical. The available version of the frame, which can be installed with nails, means that these windows can be quickly and efficiently fitted into the building, regardless of whether it is a new or renovated property.
