Roof inlet gravity DrainBox DN125 vertical, with bituminous collar d500mm HL63H/2

Roof inlets for gravity drainage

This vertical gravity roof inlet DrainBox DN125 with a bituminous collar with a diameter of 500 mm is a reliable solution for effective drainage of water from flat roofs. The construction based on a durable, corrugated polypropylene (PP) housing ensures durability and resistance to weather conditions. Adjustable height (100-160mm) allows for precise adjustment to thermal insulation, which facilitates installation and minimizes the risk of errors.

This inlet is particularly recommended for use on roofs with a corrugated sheet metal structure. The bituminous collar d500mm provides a tight connection with the roof covering, preventing leaks and guaranteeing long-lasting protection against moisture. Thanks to the flow rate of 12.20 l/s, the inlet effectively copes with heavy rainfall, protecting the building structure from water damage.

• Universal mounting: Compatible with DN125 spigot connections and HDPE welded systems, providing flexibility in the selection of other installation elements.
• Durable construction: Made of high-quality polypropylene (PP), resistant to corrosion and mechanical damage.
• Tightness: Bituminous collar d500mm ensures a secure and tight connection with the roof covering.
• Height adjustment: The ability to adjust the height in the range of 100-160mm makes it easier to adapt to the specifics of the roof and thermal insulation.
• Efficiency: Flow rate of 12.20 l/s guarantees effective water drainage even during heavy rainfall.
• Easy access for cleaning: Equipped with a Laubfangkorb drain grate with a diameter of 145mm, which catches leaves and other debris, making maintenance easier and preventing clogging of the system.

This roof inlet is not only a functional element, but also an investment in the safety and durability of the roof.
