Differences between a rough out measurements and the rebate measurements of your opening
The rough out measurements and rebate measurements refer to different aspects of a door opening and are used for different purposes.
Rough out measurements are the measurements of the rough opening in the framing of the wall before any door or window is installed. These measurements are used to determine the size of the frame that can be installed and ensure that it will fit properly in the opening. Rough out measurements typically include the width, height, and depth of the opening.
Rebate measurements, on the other hand, refer to the measurements of the area within the door frame where the door will actually be installed. This includes the width, height, and depth of the space where the door will be installed, as well as any additional measurements necessary for installing hardware such as hinges, locks, and handles. Rebate measurements are used to ensure that the door will fit correctly within the frame and that the hardware will be properly aligned.
The main difference between rough out measurements and rebate measurements is that rough out measurements refer to the overall size of the opening, while rebate measurements refer to the specific space within the door frame where the door will be installed. Both measurements are important for proper door installation, and it's important to take accurate measurements of both before selecting and installing a door.
