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.

Ordered 6x6 base yrim not 4x4 base trim
Would RecommendI have ordered 6x6 base trim for the 3rd time. Hoping to get the 6x6 base trim this time when it's supposed to come in on the 26th. The store has helped me through the ordering of the Trex 6x6 base trim. For some reason, they keep sending 4x4 base trim!
