Aquaflow Hopper Square / Round

Hopper – Square to Round

The Plastic Hopper Square to Round is a versatile rainwater component designed to convert a square profile gutter run into a round downpipe outlet. It combines the functionality of a hopper with a profile adaptor, enabling effective rainwater transition while enhancing system performance and appearance.

Manufactured from high quality uPVC, this hopper adaptor delivers excellent weather resistance and long term durability. The hopper chamber collects water from the square gutter and directs it smoothly into the round downpipe, helping to control flow and reduce the risk of splash back or overflow during heavy rainfall.
