If you’re not as familiar with doors as we are, there are probably a couple of terms you don’t know. Check out this diagram of an exterior door and familiarize yourself with the lingo!
1. The Door or Slab is the main element of this unit. It refers to just the door itself, without the jamb.
2. Almost all wood doors will be built with rails and stiles - these are the main structural components of the door. Rails are horizontal, stiles are vertical so the Top Rail is a horizontally positioned component at the top of the door.
3. The Stiles are the vertically positioned structural components of the door.
4. Lites are glass portions of a door.
5. Panels are the components within the rail and stile structure. Panels can be raised or flat, and they can have details like molding, or just plain like a shaker-style-door.
6. The Drill on the door refers to where the lock-set and passage hardware will go.
7. The Lock Rail adds strength to the door as a horizontal cross member.
8. The Bottom Rail or Kick is the horizontal rail at the bottom of the door.
9. The Casing or Jamb is the frame around the door.
10. The Hinges are what hold the door onto the jamb.
11. A Mullion is a stile that is positioned between the panels.
12. The Threshold or Sill is a component of an exterior jamb. It sits at the base of the door unit and should fit flush with interior flooring.
