20Ft, Box Gutter, 1" x 8" x 10" x 8" x 1", 26 Gauge.

A box gutter is ‘trapped’ between two roofs that feed rainwater into it. The water is drained via downpipe nozzles, or via a sumps & downpipes built into it.A good box gutter design will have falls along its length, together with sumps to collect water before it is fed into large downpipes. There will also be an overflow facility on the side or the end. This is very important – so that water will overflow externally to the building, rather than flood into the roof cavity. Available in 26 and 24 gauge only. Standard lengths are max 20 ft.
