This element is a practical solution for extending the height of roof drain bases, ensuring compatibility with various structural layer arrangements. The HL3400 extension, made of durable polypropylene (PP), is compatible with the popular HL3100 and HL5100 series drains, as well as other HL system elements, such as HL8500 extensions and the HL150 drainage ring. This allows for the creation of a comprehensive and effective roof drainage system.

Versatility and system compatibility

The extension, with a height of 200 mm and a diameter of 146 mm, equipped with an O-Ring, ensures a tight connection and reliable operation. Its design allows for easy connection with other elements, which translates into flexibility in design and installation. This is particularly important when implementing unusual architectural solutions or modernizing existing installations. Thanks to its compatibility with various drain series and additional elements, it allows for cost optimization and simplification of the installation process.

Installation and application

The HL3400 extension is used both in new constructions and during renovations. It is ideal for use on terraces, balconies and flat roofs. Installation is simple and intuitive, and the included O-Ring ensures a tight connection. Additionally, the "FixIT" mounting kit (HL619) is available, which facilitates precise positioning of the extension or the base frame of the roof drain. The weight of the extension is only 0.264 kg, which makes it easy to transport and install at height.
