It is important to carefully review any product attachments or guidelines provided by the manufacturer to ensure that you have a clear understanding of the size and dimensions of the door unit. This will help you to properly measure the rough opening and ensure that the door unit fits properly.
It is also important to carefully measure the actual door unit itself, as the nominal size may not always match the actual dimensions of the unit. By accurately measuring both the rough opening and the door unit, you can ensure that the unit will fit properly and function as intended.&nbsp;
