What are vinyl post caps?

Vinyl post caps are decorative covers that are placed on top of the posts of a vinyl fence. They are typically made of the same material as the fence itself and are used to protect the tops of the posts from the elements. Post caps are available in a variety of styles and colors to match the design of the fence, and they can be used to add a decorative touch to the overall look of the fence. In addition to protecting the tops of the posts, post caps can also help to prevent water from getting inside the posts and causing them to rot or become damaged over time.
