An advantage of covered hardware is that the hinge elements, which are visible in standard windows, are not visible in windows from Wiktorczyk with covered hardware from G-U. The problem of selecting the cover colour disappears completely. The window looks very elegant. This hardware can be opened at an angle of almost 100 degrees. It can be equipped with anti-burglary hardware of the WK2 class.
