Description
Fence post cap 18×18 mm, green

The green 18×18 mm fence post cap is a simple finishing element for protecting the open ends of square-section posts. For fencing contractors, it is a quick way to close off the structure neatly and tidily.
The cap is made of polyethylene, a plastic commonly used to produce covers and end caps. The closed top covers the opening in the profile, and the rounded corners give the top of the post a neat appearance.
Green is one of the typical colours used in fencing, so the cap is easy to match with posts and components in a similar shade, creating a consistent finish along the whole fence line.
Applications
- Protecting the open ends of square fence posts
- Closing the profile from above and neatly finishing the top edge of the post
- Completing fences with green square posts
- Finishing posts when installing new fences and when upgrading existing ones
Caps of this type are fitted from above onto the end of the post, so before ordering it is worth making sure that the profile cross-section matches the size of the cap. The square shape with rounded corners helps the cap sit evenly on the post.

Choosing a cap for your post
When choosing post caps, the key factors are the internal dimension, which determines the fit on the profile, and the depth, which defines how far the cap goes onto the post. Checking these dimensions before installation helps avoid mistakes when ordering larger quantities.
