About this product…
Post trims are designed to wrap around the bottom of your 4-piece post wrap, providing a smooth and stylish transition between your columns and decking. These trims add cohesion and polish to your project by bridging material gaps in a visually appealing way. If you’re working on a deck or porch and want to evoke the timeless look of beveled wood without the added cost and maintenance, the adjustable four-piece post trim by RDI offers a smart alternative.
Functioning as a versatile 4x6 post base cover, this adjustable trim is incredibly easy to install and works with posts ranging from 4" to 6". It provides the aesthetic charm of traditional wood while offering the long-term durability of weather-resistant vinyl. Whether you’re finishing the base of a post or flipping it to use at the top of a 4x4 4-piece wrap, this trim delivers both function and flexibility.
Available in classic white, clay, and sand tones, these post bases add a professional touch to any deck or railing setup—ideal for both contractors and homeowners. Their snap-together design ensures quick installation, making them a go-to choice when sliding a trim over an existing post isn’t feasible.
With low-maintenance materials and a lifetime warranty, RDI’s adjustable post trims are built to last—and built to impress.
Installation Instructions:
Simply snap the four pieces together to assemble and disassemble with ease.
