The Wavin Osma RoundLine External Stopend 112mm (Dia) Black is a standard domestic rainwater semi-round hanging gutter system. It is manufactured from unplasticised polyvinyl chloride (PVC-U) 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 163m² (with one downpipe). The external stopend has no clips, as it is fitted into another fitting instead, which is most commonly a running outlet. When clipped directly onto the gutter, it forms a watertight, sealed end. 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.
