Roof drain DN50/75, eccentric with bituminous collar fi420mm, siphon, round clamping frame and stainless steel cover HL80.1HR

Roof inlet – reliable drainage for terraces and balconies

This offset roof inlet DN50/75 with a bitumen collar is a comprehensive solution for draining water from flat surfaces. Designed for both professional installers and end-users, it provides effective and durable drainage for terraces, balconies and other surfaces exposed to precipitation. Equipped with a water trap, it prevents unpleasant odors and ensures efficient system operation.

Construction and installation – flexibility and tightness

A key element of this inlet is the 420 mm diameter bitumen collar, which allows for a tight connection with the bituminous waterproofing layer. This guarantees no leaks and long-lasting protection against moisture. The DN50/75 drain pipe has a drain angle adjustment range of 90 degrees, providing great freedom during installation and adaptation to specific conditions. The round grate cover can be adjusted in height within the range of 20-70 mm, allowing for perfect adaptation to the selected surface thickness.

An additional advantage is the possibility of expanding the system with additional elements such as straight and collar extensions (HL340N, HL85N, HL85NC, HL85NH) and a heating set HL82. This allows you to adapt the drainage to specific roof layer configurations and ensure optimal functionality throughout the year. A water flow rate of 0.5 l/s ensures effective drainage even during heavy rainfall. Thermal resistance up to 85°C makes the inlet resistant to high temperatures.
