Ratings may include incentivized customer reviews.
What Customers Are Saying
Customers overwhelmingly praise these post sleeves for their clean, professional appearance and seamless integration with composite railing systems. Most find installation straightforward with the snap-together two-piece design, and many highlight how effectively they conceal gaps between posts and decking. However, some report the plastic feels thin and lightweight, and several encountered sizing confusion between four-point-five and four-inch post dimensions. Despite these concerns, the vast majority consider them highly effective at finishing deck aesthetics.

Great option to replace old post skirts
Would RecommendFinally, Trex has started making their post skirts in two pieces that snap together! (And hey Lowes, would be nice if you'd update your online description to mention this!)
