The TC-40 Air Tight Door has two specific designs: the automatic door bottom and the multi-point lock.
The automatic door bottom creates an airtight system for the door, preventing air and water infiltration. The system uses a sponge seal which is automatically lowered with a high quality mechanism when the door is closed. This ensures a tight seal at the bottom of the door, which can adapt to floor surface changes over time.
