Fit and Secure the Trim Piece

What happens here

Take the freshly cut trim piece and carefully place it into its intended position around the deck post and against the stair structure. Apply firm pressure to ensure it fits snugly and flush with all adjacent surfaces. Once properly aligned, secure the trim piece using an impact driver and appropriate decking screws. Ensure the screws are driven in carefully to avoid stripping or damaging the composite material, and consider using color-matched screws for a seamless appearance.

Goal: Securely attach the custom-cut trim piece for a finished corner.
