The Ideal 4000 system offers a movable post with a width of 162 and 126 mm. The solution most often chosen by customers is a standard post.
However, it is worth considering using a narrower post and central handle in your windows. The biggest advantage of the 126 mm post is the larger glazing area.
This may not be important for large windows and balconies, but for narrow leaves, every additional centimeter of glass is important. The aesthetic value of this solution is also important.
The 126 mm movable post is also available in windows and balconies made in the Renovo system.
