Keep noise, dust, and drafts out of your space. The large, dense seal on this weatherstripping muffles sounds that would otherwise travel through gaps in your door frame. Made of closed-cell neoprene foam, the seal is less permeable than solid neoprene or vinyl seals and compresses more tightly against uneven surfaces. It resists abrasion, water, and oil, and holds up to extended outdoor use without cracking or breaking down. It’s also resilient, so it quickly bounces back to its original shape. Mount it to the sides and top of a door frame.
