Description
This is a push fit round fence post cap designed for small round metal fence posts.
The cap has a 48 mm top head with a conical roof so rainwater can run off easily. Under the cone there is a short reinforced cylindrical section to make the cap stronger when tapping it into the post.
The lower insert section has side retention bumps that help the cap grip inside the tube. The top area is reinforced, while the lower insert has an internal relief hole to save material.
The cap is intended to be gently tapped into place with a rubber mallet or with a piece of wood placed on top.
