Basic Interior Door Parts

Every interior door, regardless of its style, consists of several fundamental parts. Understanding these basics will help you navigate the more complex components of specialized door types.

Here are the basic interior door parts names and their functions:

Door Slab

The door slab, also known as the door leaf, is the main body of the door. It’s the visible part that swings or slides to open and close. The door slab can be made from various materials like wood, hollow core, or solid core.

In solid wood doors, the slab is made from a single piece of wood. In hollow core doors, it’s composed of a lightweight, hollow frame with a thin layer of wood or veneer on the surface. Solid core doors, on the other hand, have a dense, solid material filling the frame.

Door Frame

The door frame, or door jamb, is the structure that holds the door in place. It’s typically made of wood or metal and consists of three vertical pieces: the side jambs and the head jamb. The frame is installed around the door opening and provides the track for the door to move along.

The frame also houses the hinges and the strike plate, which is the metal plate where the latch or lock mechanism engages when the door is closed.

Door Hardware and Accessories

Door hardware and accessories not only enhance the functionality of interior doors but also contribute to their aesthetic appeal. Let’s explore some of the most common interior door parts names in this category.

From handles to hinges, each component plays a crucial role in the door’s operation and appearance.

Doorknob or Door Handle

The doorknob or door handle is the most visible and commonly used part of an interior door. It’s used to open, close, and lock the door. Doorknobs come in various styles, materials, and finishes to match different decor themes.

Some common types include lever handles, knob handles, and pull handles. Each type offers different levels of grip and ease of use, catering to various needs and preferences.

Door Latch and Lockset

The door latch and lockset are responsible for securing the door in the closed position. The latch is a spring-loaded mechanism that engages with the strike plate in the door frame when the door is closed. It holds the door in place until released by the doorknob or handle.

Locksets, on the other hand, provide additional security by allowing the door to be locked from both sides. They consist of a lock mechanism, a keyhole, and a thumbturn or deadbolt. Some locksets also include features like a privacy lock or a passage lock, depending on the door’s intended use.

Door Hinges

Door hinges are the unsung heroes of the door world. They allow the door to swing smoothly and safely along the door frame. Hinges come in various types, such as butt hinges, pivot hinges, and concealed hinges, each with its unique design and function.

Butt hinges, for example, are the most common type and consist of two leaves held together by a pin. They are typically used on interior doors and can be surface-mounted or mortised into the door and frame.
