Description
Fence post cap 18×30 mm, black

The black 18×30 mm fence post cap is a practical finishing component for rectangular posts. It fits onto the top of the post, closing the open profile and giving the fence a neat, uniform finish.
The cap is made of polyethylene. Plastics of this type are commonly used to protect the ends of profiles because they are lightweight, easy to work with and do not corrode. Closing the profile helps prevent water, leaves and debris from entering the post.
Applications and selection
- Finishing the tops of rectangular 18×30 mm fence posts
- Neatly closing profiles in fences, railings and structures made from hollow sections
- The black colour suits dark-coloured fences and joinery in understated styles
- Sold individually, making it easy to order the exact quantity needed for a project
The cap is lightweight and qualifies as a small parcel, making it easy to store and transport alongside other fencing accessories. Before ordering, compare the internal dimensions of the cap with the cross-section of the post.

The detailed dimensions of the cap, including internal and external dimensions, overall height and insertion depth, are listed in the specification tables below.
