Install Inner Corner Trim

What happens here

Install a piece of narrow composite trim designed to cover the inner corner where the two sections of composite boards meet the metal post. This piece typically fits snugly into the corner to hide the cut edges and provide a finished appearance. Position the trim, ensuring it's flush with the top and bottom of the boards, and secure it by driving screws through it into the metal post and/or the adjacent composite boards using the Makita cordless drill.

Goal: Cover the exposed edges at the inner corner for a finished look
