Under-door gaps are one of the most common entry points for mice and rats, and a typical under door seal strip is no match for the gnawing of these pests. The Xcluder Low-Profile 36-inch Door Sweep is made from durable, heavy-duty materials to protect your home or office from mice, rats, and other pests. The rust-resistant metal frame houses an industrial rubber weather seal filled with Xcluder's rodent prevention fill fabric, a combination of steel wool and poly fibers, creating an impenetrable barrier for rats and mice. The Low-Profile Door Sweep fits doors up to 36 inches wide and can be cut to smaller sizes using standard tools. It seals gaps up to 1-inch (25.4mm) and features installation adjustability up to 1/16 inch (2.4mm). Easy to install and with a clean, upscale, discreet aesthetic, the Xcluder Low-Profile Rodent Proof Door Sweeps are ideal for protecting garages, restaurants, schools, retail stores, and any building where maintaining a pest-free environment is essential.
