● The joint with drain is an essential accessory to complete the gutter system, as it allows the rainwater collected by the channel to be evacuated.

● The accessory, made with the Bi-System assembly system, can be applied by gluing or with a gasket (which allows better expansion of the channel in the presence of temperature changes).

● Downpipes with a diameter of 63-80 mm can be glued into the lower part of the joint with drain.

The gutter system has the function of collecting rainwater from the roof and conveying it within a disposal network made up of downspouts, wells, siphons and underground pipes.
