If your garage door's bottom lip has started to let the outside world seep inside, do something about it. Take care of the problem from the bottom up with a Park Smart Garage Threshold Seal.

This threshold seal lays a flat vinyl polymer strip underneath where your garage falls when closed. All-weather Liquid Nails adhesive permanently attaches Park Smart Garage Door Threshold Seal to this area, providing a 1/2" thick seal to keep out weather, dirt, dust, and bugs. 3 colors and 6 lengths are available to fit any size garage, though the Park Smart Garage Threshold Strip can be cut down if necessary. For strips below 50' long, Park Smart even includes a caulking gun at no extra charge!

An old garage is no excuse for letting uncomfortable temperatures and wildlife into the safety of its interior. Replenish the weather-sealing and better protect your garage's insides with Park Smart Garage Threshold Seal. Backed by a Lifetime Warranty.

The directions were great and the product was very easy to install. I am well satisfied with the Threshold Seal and look forward to a much warmer garage this winter when the wild winds blow here in Michigan.
