Architect's Choice Windows & Doors - Anatomy of an Entry Door

Entry doors seem simple but there are actually several parts that make up the whole door. As you shop for your new entry doors, we explain all the components so you’re completely ‘in the know’ when you make your purchase. Our Architect’s Choice team are factory trained and can answer all your questions. Stop into our showroom today and shop our selection of front doors, patio doors, side doors, garage entry doors, sliding glass doors and more.

Top Rail

The top horizontal portion of the door is called the top rail. It connects the lock stile and hinge stile.

Lock Stile

The lock stile is the vertical part of the door and wide enough for the lock and hardware to be mounted onto.

Lock Set

The lock set consists of several components including the handle or knob, latch, deadbolt, and keylock.

Panels

The door panel is the whole door that swings back and forth. The rails, mullion and stiles divide the large door panel up into smaller panels.

Mullion

The vertical component on either side of the door panel that divides the door into different sections is called the mullion.

Bottom Rail

The bottom rail is the bottom, horizontal part of the door that is almost flush with the floor.

Frame

The door frame surrounds the entire door and consists of the head, jamb, and sill. Door frames are usually made of wood but can also be aluminum, composite, or fiberglass.

Hinge Stile

The hinge stile is the vertical part of the door on the side where the hinges are mounted.

Hinge

Hinges allow the door to swing open and closed. Most doors have three hinges but larger doors have four or more. Hinges traditionally match the finish of the lock components.

Door Stop

The door stop moulding is attached to the frame and stops the door from swinging through the frame.

Jamb

The door jamb is the section around the door frame that keeps the door frame stable. The jamb also keeps the frame square so the door is aligned and level, allowing it to bolt and lock.

Sidelight

A sidelight is a narrow panel of windows or glass alongside a door. Sidelights are optional when purchasing your entry door and can flank one side or both sides of the door.

Threshold

The threshold is traditionally made of material such as metal so it can withstand foot traffic. It is sloped to the outside to direct water away from the house or building.
