About this product…

Post trims are pieces of material that wrap around the bottom of your beams or balusters in order to bridge the gap between your columns and your decking. Post trims can offer more cohesion or an aesthetically pleasing transition from the materials of your columns to the materials of your decking. If you’re working on a deck or porch project and are looking for a classic, understated or subtle style post trim, consider this vinyl option for a fraction of the hassle and cost of real wood. Not only is the vinyl option cost-effective, these products are crafted using weather-resistant vinyl, making this product durable and incredibly low-maintenance.

Since these trims are one piece, you must slide the baluster over or through the existing trim. These trims do not work with balusters that are pre-existing, or already installed in your decking. Within minutes, you now have a polished looking trim fit for your beautifully finished deck. Plus, you’ll save yourself stress over service and maintenance of your RDI trims with their lifetime warranty.

4” x 4” Low Profile Post Trim Installation:

  • Simply secure the trim into your decking, then slide the baluster into its center.
