what does prehung door mean

A prehung door is a door that comes with a frame and is ready to install. The door slab is already hung in the frame and pre-cut for the doorknob and the strike plate. Prehung doors come with everything you need to hang the door, including hinges attached to the door frame, and the doorknob holes already cut. They are recommended for rough door openings and exterior doors because they are easier to fit and come weathertight from the factory. Prehung doors can be installed quickly and easily, making them a convenient option for those who dont have much experience with door installation.
