What Customers Are Saying

Customers overwhelmingly praise this product for delivering a polished, professional finish that transforms deck aesthetics. Most highlight how it seamlessly integrates with post sleeves, hides the junction between post and decking, and creates a cohesive, high-end appearance. Many appreciate the easy snap-together installation and lightweight composite design. The color matching is consistently noted as exceptional. Some mention sizing confusion, as it fits 4.5x4.5 sleeves rather than standard posts, and a few note visible seams on the two-piece design. Overall, reviewers strongly recommend it for upgrading outdoor spaces.

Ordered 6x6 base yrim not 4x4 base trim

Would Recommend

I 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!
