Ratings & Reviews for Trex 4-in x 4-in Classic White Composite Deck post base trim
Ratings may include incentivized customer reviews.
What Customers Are Saying
Customers overwhelmingly praise these post sleeves for delivering a professional, high-end aesthetic that transforms deck appearance with a crisp, polished finish. Most highlight the seamless integration with railing systems and flawless color matching. Many appreciate the updated two-piece snap-together design, noting it's intuitive and easier to install than expected, with tight seams barely noticeable once assembled. However, some report sizing confusion, as the product fits 4.5-inch posts rather than standard 4-inch sizes, causing gaps on older systems. Despite minor material quality concerns from a few reviewers, most find the product fulfills its purpose effectively.

Would Not RecommendDidn’t fit. Says it’s for a 4x4 post. However fits an 4.5x4.5 post. They need to put that in the name. Stop false advertising. And just say what your product is.

Simple post skirting.
Would RecommendEasy post skirting that adds a nice trim to Trex post sleeves. Only issue is that they snap together leaving a seam on two sides.

Great item when you forget to install it first!
Would RecommendI like the fact that the base trim is now available in another color besides white and that they now come in two separate pieces. Makes installation a lot easier when you realize that you forgot to install the base trim prior to installing the railings and post caps.
