18mm x 18mm Square Fence Post Cap | Grey Polyethylene
For covering sharp or unfinished post tops, this square strainer cap provides a practical way to finish and protect the top of a 18mm x 18mm square fence or support post.
The shape-specific fit helps the cap sit neatly on square posts, reducing loose movement when correctly matched to the post size. The cap supports a cleaner finish on visible fencing where exposed post ends would otherwise look unfinished.
What Are Square Fence Post Caps?
These square plastic post caps are used where exposed square posts need a durable top cover without drilling or additional fixings. They are practical for boundary fencing, railings, garden structures and site maintenance work.
