Make Relief Cuts

What happens here

After marking the cut line, the worker makes a small, short relief cut (appears as a V-notch) at the beginning and end of the marked section using tin snips. These cuts define the lateral limits of the section that will be removed and provide a clean start and end point for the subsequent step of creating locking tabs. They also help prevent unintended tearing of the vinyl when manipulating the panel.

Goal: Prepare the siding panel for cutting the main section
