Stop Snirt like snow, dirt, leaves, debris, insects, spiders, snakes, frogs, mice, rats and more from getting into your building through unsightly gaps below the doors. This new, even larger seal weatherstripping astragal is made using the same Heavy-duty, Kevlar reinforced woven polyester technology as our original size. It stays pliable in cold weather and retains its resilience for years and years, so it molds to the shape of the floor regardless how many times the door is opened and closed. It will not tear and never wears out, and we offer a limited Lifetime Warranty to prove it! And just like the original, this larger BottomSealer™ is filled with a high-density foam core that insulates against temperature changes, keeping your shop, warehouse or hangar cooler in the summer and warmer in the winter. It solves the age-old problem of door freeze-down caused by escaping heat that melts outside snow against the bottom of the door which then allows the resulting water to seep under the door and refreeze.
