It’s a remarkably sturdy piece of rubber that seals even huge garage door-floor gaps.

The Best Garage Floor Threshold Seal
Universal garage door seal
The best garage floor threshold seal is the Vat Industries Universal Garage Door Seal. Attach this rubber to the floor where the floor and door meet.

The Vat seal is more expensive than other seals, but it’s also the last threshold seal you’ll buy for years. It comes with a lifetime warranty.
This is the rubber seal that keeps out drafts, bugs, grass and noise. It also stops wind, rain, dirt and leaves from entering the garage. Drive over it and slam the door onto it, normal wear and extreme temperatures just don’t affect it. That’s because it’s made of EPDM rubber, an especially strong yet yielding type of rubber. The only real-world danger to EPDM rubber is oils and solvents, but it has to be in sufficient quantity to affect your threshold seal. Unless you pour a can of gas on this threshold, it’s not going to budge. All of the door seals in your car are made out of EPDM, so this stuff has been tested around cars.
