The most common door frame profile is a double rabbet, which are frames with two rabbets with a stop in between them. The rabbets can be equal or unequal.

These frames are designed for easy assembly by inserting the metal tabs into the appropriate slots and bending them with a hammer to hold the pieces together. They are the least expensive frame option because they are shipped disassembled, allowing them to be tightly packed for shipping and jobsite storage.
