Finishes on the WICSLIDE 75FD folding-sliding system are carefully designed for visual harmony in both open and closed positions. When open, all elements are black, the screw heads and the lower rollers are concealed by black caps. When closed, the profiles are flush and their presence is dignified and balanced. The leaves of the WICSLIDE 75FD folding-sliding system are available in two versions with sightlines of 63 mm (standard) or 73 mm (heavy-duty).
