The Wavin Osma RoundLine Internal Stopend 112mm (Dia) Black is a standard domestic rainwater semi-round hanging gutter system. It is manufactured from polyvinyl chloride (PVC) material, making it resistant to corrosive chemicals and physical impacts. The pipe is suitable for domestic or housing market where it can cover a maximum roof area of 163 square metres (with one downpipe). The internal stopend has no clips, as it is fitted into another fitting instead, which is most commonly a running outlet. It is clipped down onto the rubber seal of the fitting to make a watertight joint. The product is available in a range of colour options and also available in different diameters which fits well with all Wavin Osma pipes and fittings. The Wavin Osma vent range offers an exceptional choice of pipe and fittings including brackets, bends, junctions, access fittings, terminations and problem solvers.
