4 ~ Piece Vinyl Post Wrap by RDI for 4" x 4" Posts

If you’re not in a position to install new posts for your railing system or to slide a post sleeve over an existing post, RDI vinyl post wrap offers a simple and attractive solution. We know how it is: sometimes you don’t have as much leeway when it comes to poles or posts on your property. Maybe they were chosen and installed by a previous owner, or perhaps you simply want to update your railing system with a newer, fresher look. RDI’s vinyl post wrap will perform a quick makeover on old or unsightly 4″ x 4″ posts, transforming your railing instantly.

This four-piece vinyl post wrap comes in three neutral colors ~ White, Khaki, and Sand ~ so you can be sure to choose an option that will match the desired aesthetic for your home. Another benefit of RDI vinyl post wrap is the cost efficiency you’ll enjoy the freedom to wrap poles, rather than having them removed or replaced altogether. Whether you’re conducting a complete remodeling project or are planning on investing a single weekend afternoon on sprucing up your home, you’ll appreciate how easy this post wrap is to install and maintain.

    4 piece vinyl post wrap by RDI

    Posted by David on Oct 11 2021

    When our contractor added an overhang for our small porch, he left the support posts as 4x4 treated lumber. I added these wraps which were perfect for upgrading from a rather shabby look to a professional finish. They were easy to install and have made all the difference to finish off our entry.

    4piece vinyl post wraps

    These look fantastic. Didn’t give a 5 star because where the wraps are bent to connect to the next piece, they were bent too much and the last piece didn’t snap as it was supposed to. We added a railing system too and the screws for the brackets are holding in place. You can’t tell and there are no gaps. We purchased 3 post wraps and it was the same for each one.

    Looks good, can be a pain to install

    Posted by JoyceT on Apr 30 2021

    There is a lot of squeezing and manipulating to get the pieces to click together. Thankfully we were only dressing two posts as my husband is very much done with this product. That said, it looks beautiful.

    The 4 pieces fit perfectly on a 4x4 post after measuring the appropriate height.

    Covered Colonial Style Post

    Posted by Phil on Dec 10 2020

    The post wraps were needed to expand the width of my colonial style posts. We recently purchased new vinyl railings, the end brackets edges extended the post. The wraps work well, as directed by Deck Expressions you don’t want to over snap the areas where the post is narrow. I measured all the way up to make sure that the widths were consistent. The post wraps look great!
