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.

Lies.
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.

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.
