Solution For Large Gaps Under Your Overhead Doors

If you have a large gap under any of the overhead doors in your garage, shop, warehouse or airplane hangar, there is an effective do-it-yourself solution on the market.

The original SnirtStopper system has been sealing garage and shop doors effectively for several years, and now there are new additions to the line that will handle even tougher problems caused by uneven floors or ill-fitting doors.

The Large Premium BottomSealer is designed to seal gaps from 1.25 to 2 inches. It features a larger 1.5-inch thermal tube that provides a more heavy-duty seal on larger gaps than the regular size can achieve.

Faced with even bigger gaps? Help is on the way! The XL Premium BottomSealer has a 2-inch tube that can handle gaps up to 3 inches. And the XXL Premium BottomSealer features a 2.75-inch roll that seals gaps up to 4 inches.

The two larger models are especially effective on larger buildings such as farm shops, warehouses or airplace hangars. They also work great on large bifold or hydroswing doors.  

This new larger seal weatherstripping 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, 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 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. Save money on heating and cooling bills and keep workers more comfortable and happier with a cleaner, safer and more efficient workspace!

In addition to the obvious improvements in efficiency and safety, sealing your overhead door gap also eliminates Snirt. Snirt traditionally is the messy combination of snow and dirt that can slip infiltrates through a gap under your overhead door.

But Snirt also can be what we refer to as other “monsters” slipping into your parking or work areas. These include leaves, debris, insects, spiders, frogs and more. In short, it is time to Stop The Snirt! – and you can do it with the proper-sized BottomSealer to fit your specific needs.
