When it comes to door hardware, two things matter most: functionality and security. A doorknob or lock might look great, but if it doesn’t work properly—or worse, can’t keep your home safe—what’s the point?

Identifying Different Parts of Door Hardware

Door hardware can be broken down into two main categories: the visible pieces you see on the outside of the door, and the internal mechanisms that make everything work.

External hardware includes the classic doorknob or lever, the striking plate, and the door’s hinges.

• Doorknobs and levers: These are the parts you actually touch to open and close your door. But they’re more than just decorative. They control the internal hardware that keeps your door functioning.
• Striking plates: A small, flat piece of metal mounted on the door jamb. The latch fits into the hole in the striking plate to keep your door closed.
• Hinges: These secure your door to the frame and allow it to swing open and closed smoothly.

Internal hardware keeps your door working behind the scenes.

• Door latches: Controlled by the knob, they hold the door closed by locking into the striking plate.
• Deadbolts: A strong metal piece for added security. Think of them as the bouncer for your door.
• Interchangeable cores: The keyed locking mechanism that keeps your door secure when closed, and makes it easy to rekey your locks without swapping out the entire assembly.
