Hey there, is your old garage door seal letting in drafts, water, and dirt? Time for an upgrade! This is an 18-foot long rubber weather seal replacement made specifically for Clopay garage doors with a 'single slot' design at the bottom. It's super important - before you buy, check your current seal! If your door has a separate little channel (a single slot) for the seal to slide into, this is the right one. If it has a double channel, it won't fit. Made from durable, high-quality rubber, this seal will block out wind, rain, dust, and even help with insulation to keep your garage cleaner and drier. It's about 2 inches longer than 18ft, so you can trim it to fit your door perfectly. Installation is a two-person job but pretty straightforward: clean the track, guide the new seal in, and pull it through. Keep your garage protected the right way!
