Install Modified Trim Piece

What happens here

With the notch successfully routed, take the modified trim piece and carefully position it back into its intended place on the structure. The notch should now clear the obstruction (the metal bracket in this video), allowing the trim piece to slide into position smoothly and sit flush. The video shows the installer easily pushing the trim piece into place, confirming the modification was successful. The trim piece is now ready for final fastening (screwing, nailing, or adhesive), though the fastening process itself is not explicitly shown.

Goal: Re-install the newly notched trim piece, ensuring it now fits perfectly around the obstruction and sits flush against the structure.
