L Premium Door BottomSealer™

Finally, a Garage Door Seal that Actually Works! Seal doors tight with the StopTheSnirt BottomSealer™ and keep out snow, dirt, leaves, debris, insects, spiders, snakes, frogs and more!  Our patented BottomSealer™ technology features a high-density foam core weatherstripping astragal that’s engineered to seal, saving you money on energy by stopping cold drafts and eliminating temperature bridges. The new large size seals from .75 up to 1.5 inch gaps, and the larger 1.5 inch inner thermal tube provides a more heavy-duty seal on larger gaps than the regular size can achieve. A warmer garage means a warmer house! The BottomSealer™ also reduces freeze down by eliminating the water and snow that can melt and refreeze under the door and cause the door to freeze to the ground. Each seal is made of heavy-duty, Kevlar reinforced woven polyester that stays pliable and resilient for years. It will not tear and never wears out, and we offer a limited 25 Year Warranty to prove it! FREE SAMPLES! Got a big gap but not sure what size BottomSealer you need for your door? No problem!
