Mark Siding for Window Cut

What happens here

The worker demonstrates how to accurately transfer the required cut line. He places the vinyl siding panel, which will be installed under the window, on top of the already installed panel below. Then, he takes a separate, straight piece of siding or a suitable guide and places it against the bottom edge of the window sill or trim. By aligning this guide, he traces the exact cut line onto the panel to be cut, ensuring a precise fit without direct measurement.

Goal: Accurately mark the siding panel for cutting
