Mark and Align Aluminum Screen Track

What happens here

Carefully place the aluminum screen track on the miter saw's bed. Use a pencil or marker to indicate the exact point where the miter cut needs to be made. Align this mark precisely with the edge of the 45-degree wooden jig, ensuring the screen track is held firmly and stably against the jig and the saw's fence. This alignment is crucial for achieving the correct angle and length for your miter.

Goal: Mark the desired cut line on the aluminum screen track, then position it against the 45-degree jig on the miter saw for a precise cut.
