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.
Customer review summary generated by AI, including incentivized reviews.Says they will fit 4 x 4 post. When snapped together they measure 4-1/2 inches on the inside.
Resold damaged item
Would RecommendI bought a 4X4X48 Trex composite deck post. Inside the damaged packaging of the item, that had obviously previously been returned, was a 4X4X38 Trex composite deck post. Before Lowes resells returned items to other customers I expect the contents to be reinspected so as not to waste my time on returns. I previously pointed out damage of the same item in-store to employees. This was an online purchase. Unacceptable.

Very good
Would RecommendI liked the white composite deck post sleeve for its crisp, polished appearance that instantly upgrades a deck’s look. It’s designed to protect and cover structural posts, resisting rot, insects, and weather damage. The low-maintenance composite material stays bright over time, and installation is simple, creating a seamless, professional finish that complements various railing styles.

Measure with care
Would Not RecommendThis product was too big. I have a standard 4x4 post (actual measurement 3.5 x 3.5") with a white vinyl slip cover over it. I have no idea how this was measured, but it is way too big to fit around a covered 4 x 4 post. I do not how to find one that fits, except to measure what you have and then measure the trim.p to insure it fits correctly.
