The garage door is a common, and often forgotten, place in your home where cracks and gaps can let in unwanted moisture and drafts. This type of exposure can lead to potential water damage or a potential increase in heating and cooling costs. The Duck® Brand Metal Garage Door Bottom creates a seal under the garage door to keep out water, dust, insects and more. Featuring heavy-duty rubber, this garage door bottom won't freeze or crack, no matter what the season brings. Plus, the Duck® Metal Garage Door Bottom is designed to fit the most popular brands of metal overhead garage doors. To use, simply slide the garage seal right onto the metal track on the garage door bottom.
