The DN 110 outlet, for larger catchment areas and higher rainfall intensities.
Details
TOPWET
Vertical outlet with the PVC membrane sleeve already bonded on and a protective leaf basket fitted.
The drain arrives with a PVC-compatible membrane collar factory-bonded to the body, so the roofer welds sheet to sheet instead of trying to seal a bare plastic flange.
Supplied with a protective basket. Standard length 400 mm, with custom extensions to 1500 mm where the outlet has to travel through a deep build-up.
