Automatic door bottoms mount onto the bottom of a door and lower a seal along the length of the entire door when it's shut, but automatically raise to allow the door to swing open. They create a tight seal that prevents drafts, dust, insects, and other unwanted elements from entering the building or room.

Door shoes install onto the bottom of doors or mount onto the side of doors with fasteners. They create a stronger seal than door sweeps and block out drafts, dust, noise, and insects.
