Description
Finish it properly.
It’s a small detail, but it matters. The Post Cap 50×50 snaps neatly over hollow 50x50mm RHS posts to seal the top against water, insects and debris. Left uncapped, hollow posts collect moisture and corrode from the inside out. Cap them from day one, and you’ll protect your investment for years longer.
Why Use Post Caps?
- Prevents water ingress – stops internal corrosion before it starts
- Keeps insects out – no nests inside your hollow posts
- UV-stable plastic – won’t fade, crack or degrade in the sun
- Tool-free install – snaps into place in seconds
- Clean finish – professional look on every install
Need-to-Know:
- Suits 50x50mm RHS hollow section posts
- Flat black finish
- Included as standard in Colorbond Gate Kits
- Ready for pickup in 3–5 days
