When building a pergola using Sunlite 10 Twinwall, either in Gable or Skillion design, it's important for the roofing to last.

Sunlite 10 uses a unique roof fixing and framing method - by using aluminium end caps to close out the open ends of the sheeting and then fixing an end cap lock to support the end cap to the joiner when sheet expansions occurs.

The End Cap Lock, like all Sunlite 10 Joiners & Capping, is anodised to give the over all design years of freshness without any staining that occurs with some metals.
