About this product…

This product is both a post-sleeve and a structural post (when installed with the installation kit).

Post-sleeves are used to cover existing posts that you may have on your deck, in your yard, or around your home. If you’re looking to update a space or make your home feel more in line with your desired aesthetics, post-sleeves are a cost-effective and easeful solution, not requiring you to remove previously installed posts. One quick home improvement that will transform your whole space is upgrading old posts that support deck or porch railing systems. Using composite post sleeves from RDI, you can give your porch or deck a much-needed refresher at a very minimal cost. Simply apply the post sleeves to any unsightly, weathered, or worn down posts, and you’ll notice an instant sense of accomplishment in making your home look welcoming and refreshed. 

Made from powder coated aluminum, this sleeve can withstand all kinds of weather, including humidity, rain, snow, and extreme heat.

What is the difference between post-sleeves and post-wraps?

There’s not a huge difference in aesthetic, rather how they are installed. Which you choose typically depends on the state of your existing posts. Post-sleeves are one piece, while post-wraps are made up of multiple pieces that clasp together. Post-sleeves are the perfect solution if your existing posts allow you space to slide a cover over the top of them, and you’re looking for maximum ease and time-spent when installing. Both post-sleeves and post-wraps offer a new and fresh look to an otherwise dated or worn railing system.
