Ratings & Reviews for Trex 4-in x 4-in Classic White Composite Deck post base trim
Ratings may include incentivized customer reviews.
What Customers Are Saying
Customers overwhelmingly praise these post sleeves for delivering a professional, polished appearance that elevates deck aesthetics. Most highlight the crisp visual transition, excellent color matching with composite materials, and seamless integration with railing systems. Installation is widely regarded as straightforward with an intuitive snap-together design. However, some report fit issues with standard four-by-four posts, noting gaps or needing shims since sleeves are sized for larger dimensions. Despite this concern, most customers consider the aesthetic upgrade worthwhile and recommend the product for transforming deck appearance.

Fits Well
Would RecommendI was worried a bit about the look of the seam because they are 2 pieces. But, they fit together well. I suppose it makes it so they could be used on an existing post.
