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.

Confusing dimensions
Would Not RecommendDimensions are confusing. Even though, it’s for a 4x4 post, it’s way too big for one. I wish they’d update their labels so it’s accurate. But lumber is confusing too, since a 4x4 is actually 3.5x3.5.
