Vertical door edges may be square, with a 90-degree angle to the door face, or beveled with an 87-degree angle to the door face (usually expressed as 1/8" in 2"). Your choice of vertical door edges depends on whether the door is active or inactive.
- Active door: Active doors beveled on both sides (hinge side and lock side) offer a better fit in the frame and facilitate the door opening and closing.
- Inactive door: Inactive doors in paired openings, which are not used as frequently, are usually square on the strike side to perform as the frame rabbet on a single door opening.
