FireSafe makes the only pet door that is UL certified as a 20 minute fire barrier and installs in garage doors and walls, complying with 20 minute barrier fire codes and allowing your pets safe access to the garage.

FireSafe says that the barrier also works in the other direction, so if you're a classic car lover, like me, it will protect your pride and joy in the garage from a house fire as well.
