Fire resistant wall box

Note for system with maintained functionality in fire: Fire resistant wall box KPZ-1_PO is designed for ?re partition walls, consisting of ?re resistant gypsum plasterboard or aerated concrete structures. Its advantage is that the inlet openings are made of a softened material that ensures airtightness of the passage between the box and the cable or tube installed therein. On the outside and inside of the box is applied foaming material, which in case of ?re foams the mounting hole. This ensures the integrity and insulation ?re partitions in place of location devices. Its use thus prevents the spread of ?re in the event of ?re. The triple-threaded mounting screws are provided with metal feet for quick installation. Application of this box is mainly in buildings with increased need for protection of persons and property in case of ?re. The PO classi?cation is dependent on the speci?c placement of the box in plasterboard or aerated concrete, detailed in the new catalog – Systems with maintained functionality in ?re.
