- Measure inside width in 3 places – top, middle, bottom. Measure inside height in 3 places – left, middle, right
- Use the smallest actual opening measurements
- Check for square by measuring diagonally – A & B
- Z Frame or Trim Frame units will accommodate most out-of-square in drywall openings
- If considering Mounting Strips or hinges only, an inside mount is not feasible if diagonal measurements are not within 1/8th inch. Rather, select the L Frame or go to an outside mount.
