Extension 130mm diameter 145mm with DN40 inlet HL350.2

Extension with a height of 130 mm, designed to extend the height of the base of roof inlets and outlets. Made of polypropylene (PP), it provides a durable and reliable solution in roof drainage systems. Its diameter is 145 mm, and an additional inlet DN40 increases water flow.

This element is compatible with the popular HL72.1 and HL317 series of inlets. Additionally, using appropriate support rings (HL062B.3E) or drainage rings (HL160), it can be successfully used with roof inlets of the HL62, HL64, HL69 series, as well as HL350(.2) and HL350.0(.1)(.1H) extensions, and the HL65 series. This universal solution allows adaptation to existing infrastructure and implementation of various drainage projects.

• Versatility: Compatibility with many series of roof inlets and extensions allows for flexible adaptation to specific investment needs.
• Increased flow rate: The additional DN40 inlet effectively increases the ability to drain water, minimizing the risk of flooding during heavy rainfall.
• Durability: Made of high-quality polypropylene, it guarantees resistance to weather conditions and long-term operation.
• Design flexibility: Together with other additional equipment, it enables the creation of complex flat roof drainage systems with varied layer structures.
• Easy installation: Thanks to its well-thought-out design, the extension is easy to install and integrate with the remaining elements of the drainage system.

This extension is used both in newly built facilities and in the modernization of existing roof drainage systems. It is ideal for use in residential, commercial and industrial buildings where reliable water drainage is crucial for protecting the building structure. It can be used in combination with various types of gratings and covers, allowing the appearance to be adapted to the aesthetics of the roof.
