To ensure a water-tight, expert installation, the Deep Round External Stopend system comes with a deep round type gutter and a full line of complementary fittings. The deep gutter's enormous flow capacity makes it the best choice for places that get heavy precipitation. The deep gutter's extra benefit is less frequent upkeep and cleaning owing to the profile's form. The gutter is 4 metres long, 116mm broad, and 77mm deep. The deep gutter system may be installed with square or round pipe systems.
