About this product…

Post trims are pieces of material that wrap around the bottom of your beams or posts 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. Transform has the look and feel of a wood railing- without the hassles of wood; thus making these products resistant to rot, extreme weather conditions, discoloration and warping. These products are offered in four different colors, allowing you to have a hand in your aesthetic preferences and a more personal customization of your outdoor area. The post trim works with the Transform Post Sleeve.

These are easily installable, simply slide over the post before installing the railing. Plus, you’ll save yourself stress over service and maintenance of your RDI trims with their lifetime warranty.
