The Tsunami SealĀ® Garage Threshold Door Seal mounts to your garage floor creating the perfect seal between your door and your garage floor. The Garage Door Threshold Seal 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. The Door Seal works great with all types of garage doors including roll up doors, hinged wood doors and walk through doors. The one piece strip is permanently secured to the garage floor with the included Liquid Nails Polyurethane Adhesive and a metal caulking gun. Comes with a Lifetime Warranty.

Comments about Tsunami Seal Garage Door Threshold Seal, 18' (Brown):

Did a great job sealing the garage and was fairly easy to install. The caulk gun that came with the kit didn't work, but fortunately we had our own and were able to apply the glue.
