Fence Post Cap - Zinc

Fence Post Cap – Zinc gives timber fence posts a clean, weather-shedding finish while protecting vulnerable end-grain from rain and UV. The heavy-duty pressed steel cap sits flush on the post top to help reduce splitting and water ingress, and the zinc plating provides reliable outdoor corrosion resistance with a bright, professional look.

Key Features & Benefits

• Weather Protection: Shields exposed end-grain to limit water ingress and sun damage.
• Corrosion Resistant: Zinc-plated steel for durable protection in outdoor conditions.
• Smart Appearance: Tidy, uniform finish that completes fence lines and gate posts.
• Easy to Fit: Quick installation on new or existing posts with standard fixings.
• Paintable: Can be over-painted to colour-match (key the surface first).
