Pipes and connectors. NIAGARA Square system connector. Allows for connecting 125 square gutters to 100 round downspouts

The contemporary design of the gutter system perfectly complements modernist buildings.
The outlet connects the gutter to the drain pipe and is one of the main components of the drainage system. Its distinctive appearance, in addition to its undeniable aesthetic appeal, makes it very practical and easy to assemble. Its main function is to direct water collected in the gutters into the drain pipes. The outlet on the connector is used to connect square gutters to standard drain pipes or is used in the assembly of a concealed (in-wall) system.

The Pruszyński Company guarantees that each individual order will be produced in the same color (shade). However, due to the complexity of the coating processes, slight variations in shade may occur between individual shipments; therefore, our responsibility for color consistency is limited to a single shipment. When reordering sheets from a specific batch, please indicate on the order form or inform your sales representative that this is a continuation of a previous order and provide a color sample. To ensure color consistency between tailored roof tiles and other elements, such as flashings, please order them from a single supplier.
