Mark and Route Notch for Clearance

What happens here

Once the obstruction is identified, remove the trim piece. Using a measuring tool like a speed square and a pencil, accurately transfer the dimensions and location of the obstruction onto the trim piece. This ensures the notch will be cut in the correct spot and to the correct size. Next, secure the trim piece on a stable surface. Take a cordless trim router (e.g., Makita 18V) and carefully route out the marked area. Make multiple passes if necessary to achieve the desired depth and a clean cut, creating a recess or notch that matches the shape of the obstruction.

Goal: Measure and mark the exact dimensions of the obstruction onto the trim piece, then use a router to precisely cut out a notch that will accommodate the obstruction.
