We use it for modern installation, with combined frames. The rigid design facilitates easier installation. The inlet openings are made of flexible material, it provides an airtight seal even with inserted cables or pipes, and reduces heat loss. Suitable for low energy consumption or passive houses. Two marking points on the back of the box indicate the location of the drilling. The double-threaded retaining screws speed up installation. Before connecting the cable, the membrane, e.g. can be punched out with a screwdriver. It is not necessary to countersink the edge of the plasterboard hole before installation.
