Under-door gaps are one of the most common entry points for animals, and typical door sweeps for exterior doors are no match for the gnawing of these unwanted guests. The Xcluder Door Sweep is made from durable, heavy-duty materials to protect your home or office from animals. The rust-resistant metal frame houses an industrial rubber weather seal filled with Xcluder's Prevention Fill Fabric, a combination of steel wool and poly fibers, creating an impenetrable barrier. The Door Sweep fits doors up to 48 inches wide and can be cut to smaller sizes using standard tools. It seals gaps up to 1 3/5 inches (44.5 mm) and features installation adjustability up to 3/4 inch (19 mm). Easy to install and with an optional cover for a high-end finish, the Xcluder Door Sweeps are ideal for protecting garages, restaurants, schools, retail stores, and any building where maintaining an animals-free environment is essential.
