Garage Door Threshold

A garage door threshold creates a barrier against water, leaves, dirt and snow. This helps save energy by keeping garage warmer during winter & cooler during summer. Works with roll up doors, hinged doors and walk through doors.


Tsunami Seal® Threshold Kit, 10' Black

The Tsunami Seal® mounts to your garage floor creating the perfect seal between your door and your garage floor.

The Door Threshold creates a tight seal for your garage door which will keep leaves, dirt, water and snow from being blown under the garage door by the wind.

Also, if you have a sloped driveway or an uneven garage floor and water is seeping under your garage door, the Door Seal adds a 1/2" tall barrier to the garage floor.

The Door Seal will also help keep out unwanted insects and snakes.

By creating a better seal, your garage will stay warmer during the winter and cooler during the summer, helping to keep your energy cost down.
