Corodrain Joining Gutter x 3m

The Harcon Corodrain Joining Gutter (Roof Gutter) lasts as long as lead but is tougher and cheaper.

Corodrain Joining Gutter gives a weatherproof seal between adjacent roofs and can join any combination of double lap or interlocking slates, clay or concrete tiles with minimum disturbance to the adjacent roof. The unique design ensures that the slates don't kick up.
