What is a rabbet in door construction?

A rabbet in door construction refers specifically to a recess cut into the edge of a door frame or into the edge of the door itself. This cut creates a groove that allows the door to fit snugly against the frame, typically where the door closes. The rabbet contributes to the overall stability and alignment of the door within the frame, ensuring that it swings properly and reduces gaps that might otherwise allow air or water in.

This configuration is fundamental in door design, as it impacts the functionality and the weather-tightness of the door. By having this groove, the rabbet also facilitates the installation of weather stripping or other sealing materials, enhancing the efficiency and effectiveness of the door system. Understanding the rabbet is crucial for anyone involved in carpentry or door installation, as it plays a pivotal role in achieving proper fit and finish.
