Panel
A door panel, many times called a slab, defines the whole part of the door that swings backward and forward. Full door panels are generally divided up into smaller box-like panels, which are adjusted between the stiles, rails, and mullions.
Rail
The small horizontal part on a door panel is called rails. This door has a top, bottom, and a mid-rail.
Stile
A stile is the small vertical part located on either side of a door panel. One is called the lock stile and the other is known as a hinge stile.
Mullion
A mullion looks like a stile. It is the vertical part that distinguishes two panels located in the middle of the door between the rails.
Stop molding
Doorstop molding is joined to a door frame. It limits the door panel within the frame and saves the panel from moving right through the opening.
Hinge
This is the part of the hardware that permits the door to swing open and closed. Standard-sized doors contain three hinges, but in larger doors, there will contain four or more. The color or finish of the hinges looks like the finish of the lockset.
Borehole
A borehole is drilled into a door to put up a lockset.
Lockset
The lockset defines the handles, locks, latches, strike plates, and all the other hardware parts that permit a door to catch and lock in place. Locksets are also defined as handsets or hardware.
Head Or Header
The components of the door at the top of the door that is many times called the “top jamb” which is incorrect. It is properly known as the “head” or the “header”.
It works similarly to the jambs in that it forms a component of the door frame. It is on the top and not the side, it shouldn’t be known as a jamb.
Doorframe / Casing
The doorframe is known as the two jambs and the header together. This is the component of the door that is attached to the rough opening when mounting a door. In another way, we can say the doorframe is “casing”.
Rough Opening
The rough opening is the opening in the wall that supports the doorframe. The doorframe is attached to the rough opening with the help of shims, tiny pieces of wood that are crushed between the sides of the rough opening, and the doorframe to support it in place.
Latch
The latch is the component that supports the door closed. When you turn the doorknob or push the handle down, the operation causes the latch to be pulled into the door, permitting the door to open.
Keyhole
A keyhole is a place where you insert the key to lock or unlock the door.
Sidelight
A sidelight is a small window placed on either side of a door. They are only found with external doors only.
