Roof drain collar extension – a reliable solution for complex structures

This collar extension, designed for HL62 and HL64 roof drains, is a key element in the drainage systems of flat roofs with complex layer arrangements. It allows for precise fitting and effective water drainage, minimizing the risk of leaks and structural damage. Made of durable polypropylene (PP), it ensures long-lasting and reliable operation even in harsh weather conditions.

Design and application

The extension has a height of 300 mm and a diameter of 125 mm. It is equipped with a welded bituminous collar with a diameter of 500 mm, which facilitates a tight connection with the roof insulation. Its design allows for flexible adaptation to various roof configurations, and the material – polypropylene – guarantees resistance to corrosion and chemical agents. This makes the extension suitable for both residential and industrial construction.

Advantages and benefits
