Measure and Mark Outer Edge Trim Line

What happens here

To prepare for the final, precise trim on the outer edge of the deck, the carpenter accurately measures and marks a cut line. A tape measure is used to determine the desired distance from the edge, a speed square ensures the line is straight and consistent, and a pencil is used to draw a clear marking on the composite decking. This marked line will guide the subsequent cut for a uniform border or overhang.

Goal: Accurately mark the line for the final trim cut along the deck's outer perimeter.
