Four systems. Four ways to open.

Four rooms of one house, rendered to the drawings. The 84 is shown as a project combination with fixed lights; standard sizes and data are on each product page.

Fixed lights, sliding windows and larger combinations are made to project on the same profile series — ask us with your opening schedule.
