Arched Top Cap for Garden Fences Our 50mm x 12mm dome top caps are the horizontal timber pieces that sit along the top edge of fence panels, helping to protect the panel and give a neat, finished appearance. They are ideal for replacing rotted or damaged top caps on dome‑top and concave fence panels. Designed with a subtle curved arch profile, they provide a neat, protective finish that follows the shape of arched fencing panels. Manufactured from pressure‑treated timber, these capping rails help protect fence panels from rot, fungal decay, and insect infestation, extending the lifespan of your fencing and helping to prevent water ingress at the top of the panel. As with all wooden products, exposure to the weather may cause natural fading over time. Further staining is recommended if this occurs to maintain appearance and protection.
