Automatic Door Bottoms

Automatic Door Bottoms are specifically designed to seal the gap under doors and provide the best sound control possible. Our door bottoms are built to last. The thick rubber seal drops upon closing of door to create a tight seal and raises automatically up when the door is opened, ensuring smooth operation and preventing door drag.
