Tired of cold drafts, leaves, rainwater, or even little critters sneaking under your garage door? This M-D Vinyl Threshold Kit is a simple and effective fix. It's a 10-foot long strip of durable gray vinyl that you install along the floor at the bottom of your garage door. When the door closes, it presses down on the threshold, creating a seal that blocks out wind, dust, snow, rain, and pests. It's 3.5 inches wide and about half an inch high. Installation is pretty straightforward: the kit includes a tube of silicone adhesive. You just clean your floor, apply the adhesive, and press the threshold into place. You can even cut it to the exact length you need with a hacksaw. It works with new doors or to replace an old, worn-out seal. A cheap and easy DIY project that can make your garage more comfortable, cleaner, and energy-efficient.
