Extra-long drain connectors in TPE

Wallbarn can also supply drain connectors with a 600mm long shank, where outlet pipes are passing through things such as thick insulation or industrial metal roofs.

Fitted and secured in exactly the same way as the standard drain connector, being sandwiched between two layers of waterproofing membrane, they are designed to pass through the entire section of roof and into the downpipe, and so eliminate the need for multiple connections and extension fittings (which always carry the risk of leaks around each connection).

Leaf guards & gravel excluders will also be required for extra-long connectors.
