Seal Garage From Heat and Cold
With Garage Door Threshold

Just install a Garage Door Threshold under the door. Made of top-quality rubber, it installs in minutes (no tools needed) with the supplied adhesive. This threshold can be driven on, doesn’t mind hot or cold weather and resists gas and oil spills. Your garage will stay warmer in winter and cooler in summer. 3 w x 1/2 h x 10’ L.
