Round overflow spout with PVC collar — TWC 75 PVC
Through-parapet spout with a bonded PVC sleeve and protective grille — the roof's pressure relief.
An overflow spout is not optional on a flat roof: it is what stops a blocked outlet turning rainfall into a structural load. This one comes with the membrane collar bonded on and a grille fitted.
Standard length 600 mm, extendable to 1500 mm for thick parapets.
