Despite confidence in earlier measurements, the builder reassesses the cabinet, using a level to verify alignment. Discovering a quarter-inch discrepancy near the top, he carefully removes and adjusts screws, lifting and re-positioning the cabinet to ensure it is as level as possible. Even with these efforts, the overall wall and ceiling irregularities make perfect alignment challenging. He accepts minor imperfections, trusting that visual inspection from a distance will suffice. The use of multiple levels helps confirm that the cabinet is now properly aligned.
