What Customers Are Saying

The Trex Composite Deck Post Caps are generally well-made and durable, providing a polished, finished look to the deck. Many customers found them easy to install and a good fit over the post sleeves. However, some experienced issues with the caps being too large, cracking, or not securely attaching to the posts. Overall, the caps appear to be a suitable choice for completing the deck, but customers should ensure they purchase the correct size and may need to use additional methods to firmly secure them.

Perfect fit for 4.5" square post

Would Recommend

Bought these to replace the post caps on my 15-year-old Trex deck posts, which had been made from Trex's original composite and were apparently quite delicious to squirrels :-). Be sure to note that although these are labeled for 4"x4" posts, the true dimensions of the posts that they fit are 4.5" square. I also like that they're now made from a much harder, tougher material. I think my squirrels might chip a tooth on them...
