Description
Fence post cap Ø 51 mm, black

The black Ø 51 mm fence post cap is a simple finishing component that closes the top of a tubular post and gives the fence a neat, complete appearance. For installation companies, it offers a practical solution for closing posts in fences, railings and tubular structures made from 51 mm diameter tubes.
The cap is made from polyethylene, a plastic commonly used for protective and finishing components. Caps of this type fit over the end of a post to close the open end of the tube and protect its interior from dirt. The smooth, uniform black surface helps create a consistent appearance across all posts in the installation.
Applications and selection
- Finishing fence posts with a diameter of 51 mm
- Protecting open tube ends in fences and tubular structures
- A uniform black appearance for posts throughout the installation
When selecting a cap, use the external diameter of the post as a guide: this cap is designed for 51 mm diameter tubes. The product is sold individually, 1 piece, allowing the quantity to be matched precisely to the number of posts in the installation. Its compact size and low weight make storage and transport easy, while the black colour complements many fencing systems.

Dimensions at a glance
The dimensional drawing makes it easy to check the fit on the post: the internal diameter d determines the fit on the tube, while depth h indicates how far the cap fits over the post. The full measurements are provided in the specification tables below.
