Drain for gutter comprising inner and outer flanged tubular parts, includes drainage passage for any water accumulated in space between flanges

摘要

Water can flow through a passage from the space between the two overlapping flanges (3, 5) on the tubular parts into the outer tubular part (4). Part of the gutter base is clamped between the two flanges when the inner tubular part (2) is fitted inside the outer tubular part.
