What Customers Are Saying

Customers overwhelmingly praise this deck post trim for its clean, finished appearance and seamless color matching with composite systems. Most highlight the ease of the snap-together installation, noting even inexperienced DIYers can assemble it quickly. Many appreciate how it hides post-to-decking junctions for a polished look. However, some report fit issues, as the product is designed for 4.5-inch posts rather than standard 4-inch posts, causing gaps or mismatches. A few mention concerns about material quality and visible seams in the two-piece design. Despite these drawbacks, most customers consider it an effective finishing solution.

Great option to replace old post skirts

Would Recommend

Finally, 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!) I bought these to replace the rotting, crumbling original composite one-piece skirts on my 15-year-old Trex deck. They snap together quite tightly (takes a little effort and just the right alignment) and look perfect. Note also that they are just about a quarter inch narrower around the bottom than my original sleeves, so the...
