● The installation of the gutter system may require the use of an external corner in case of a change of application direction to 90°, in correspondence with the external junction of the perimeter pitches of the roof. The external corner is assembled to the gutter profiles using exclusively the gluing system.

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.
