Installing Deck Lighting, Deck Railings, and Final Walkthrough!

What happens here

Once the railing posts are securely fastened, complete the installation by adding the post caps and base trim. Slide the one-piece base trim around the bottom of the post, covering the mounting hardware for a clean finish. Then, place the post cap on top of the post. This finalizes the aesthetic and protects the post from weather elements.

Goal: Complete the aesthetic finish and weather protection for the railing posts.
