Jin&Bao Garage Door Threshold Floor Seal Gives You a Clean and Tidy Garage ?An easy DIY project to keep your garage dry, quiet and clean. Highly durable and able to withstand being driven over by most vehicles. ?The garage door threshold seal has been designed to form a watertight seal between the garage door and the floor. ?Energy costs may be reduced as a result of heat conservation (seal prevents drafts, cold air, snow, and wind-blown rainwater from entering the garage through the gap under the garage door). Please Notice: Due to some factors such as long-distance transportation, the threshold weather stripping may appear slightly curved. This is a natural phenomenon because the material is natural rubber. Adhesive/cement necessary for installation is not included.
