The upper strip is used to stiffen the assembled cabinet door structure. By combining two vertical handles, the top and bottom strips have a big impact on the durability and performance of the entire system. This type of profile is often called “horizontal door profiles “. The fixing screw is screwed into a rounded groove in the profile. A 4 mm thick screed must be glued to a special slatted fastening. This closes the contour of the future cabinet door.
