You can freely enter the length of your new window sill from 300 to 7,500 mm and thus perfectly adapt it to the window dimensions. You choose the depth or overhang from a list of 50 to 400 mm. Among other things, the thickness of the wall plays an important role in the dimensions of the window sill. For the ideal depth, you need to know the depth of your wall and how much the window sill should protrude beyond the wall. From a length of 2,500 mm or more, the bench is delivered in two parts, for which you need a connecting piece. You can also order so-called sliding ends for a neat finish.
