Ratings & Reviews for Trex 4-in x 4-in Charcoal Black Composite Deck post base trim
Ratings may include incentivized customer reviews.
What Customers Are Saying
Customers overwhelmingly praise these post sleeves for dramatically improving deck aesthetics, delivering a crisp, polished, professional finish that seamlessly integrates with composite systems. Most highlight excellent color matching and the straightforward snap-together design that allows easy installation by anyone. However, some report sizing confusion, noting the sleeves fit 4.5-inch posts rather than standard 4-inch posts, causing gaps or mismatches. A few mention the plastic construction feels lightweight but inexpensive, and some note visible seams. Despite these concerns, most customers consider the product worthwhile for its visual transformation and installation simplicity.
