<p>Gutter lengths having a semicircular cross-section and upwardly extending sides, with curled or similarly bent upper edges, and coupling elements having portions adapted for tightly engaging the ends of the gutter lengths, are assembled together to form a gutter structure. At least one of the coupling elements, designed to compensate for the thermal changes in the gutter length, is fitted with a downspout.</p> |
