The four-sided flame-retardant fiberglass lightweight concrete ducts can be mounted on OBO mounting systems and thus offer the greatest possible flexibility when routing cables in escape and rescue routes (installation duct in accordance with DIN 4102 Part 11) or in electrical function maintenance (in accordance with DIN 4102 Part 12). This means that obstacles from other trades such as heating, ventilation and sanitation can be elegantly circumvented. Installation under the ceiling is easy with U-shaped hanging posts and a bracket or on a U-cross profile suspended with threaded rods. The OBO BSKH is simply laid loosely on top. Pre-assembled connecting fittings ensure quick assembly on site, loosely placed covers for quick inspection and subsequent use.
