Description
Fence post cap 20×20 mm, black

The black 20×20 mm fence post cap is a finishing component for posts and profiles with a square cross-section. It is fitted onto the top end of the post, neatly closing the open profile.
The cap has a lid-style design with rounded corners. It is made of polyethylene, a material widely used for protective and finishing components that work outdoors. The black colour is neutral and suits most fences and balustrades made from square profiles.
Applications and selection
- closing the top edge of fence posts with a square cross-section
- finishing square profiles in fences, balustrades and light structures
- protecting the open end of the profile against dirt getting inside
Caps of this type are selected to match the internal dimension of the profile, so it is worth checking the cross-section of the posts you are using before ordering. A cap fitted on the top end of the post is both a decorative element and a protective cover for the open profile.

Polyethylene caps are used in fencing and balustrade installations as a quick-to-fit finish for profiles. For installation companies, this is a small item in the range that complements an order for posts and allows the job to be completed with a uniform finish.
