Capacity where it is needed most.
Box gutters are square or rectangular channels built into the roof edge or parapet rather than hanging below the fascia. They are common on flat and low-slope commercial roofs and on some older buildings, where they provide high capacity while remaining hidden from view. Proper sizing, lining, and drainage are essential to their performance.
