Trex Post Flash 4×4

The Trex Post Flash 4×4 is designed to protect and finish your composite deck posts with a clean, polished look. Made to fit standard Trex Post Flash 4×4 posts, this post flash covers the base of the post where it meets the decking surface, creating a seamless transition that keeps your outdoor space looking modern and professional.

Built from durable composite materials, the Trex Post Flash resists weather, rot, and fading, just like Trex decking. It shields the vulnerable area around the post from moisture and dirt while adding extra stability and style. Once installed, it requires no maintenance, no painting, staining, or sealing needed.

Perfect for homeowners, contractors, and deck builders, the Trex Post Flash 4×4 is ideal for both residential and commercial projects. It’s available in colors that coordinate with Trex railing and decking systems, so you get a unified, high-end finish across your entire deck design.

Installation is quick and simple, making it a smart upgrade for new decks or replacements. With Trex, you don’t just protect your investment, you make it last longer while keeping it beautiful.
