Hi-Front Quad gutter (also know as Big Front Quad gutter) is manufactured from ZINCALUME® and COLORBOND® steel. Similar to standard quad gutter, the visible side of the gutter is substantially higher. For use in both industrial and residential situations, Hi-Front Quad Gutter is primarily a residential product. Available in a slotted or plain finish. A slotted finish prevents water backflow in case of a blockage in the gutter or downpipe.
