This heavy-duty door draft stopper measures 37 inches long by 3.5 inches wide and weighs 2.3 pounds, making it heavier than typical draft stoppers for improved performance. Fits standard 36-inch doors and covers gaps up to 3 inches wide. The weighted construction uses polyester wadding and ground stone to increase density and block drafts effectively. The neutral gray exterior complements most room decor. In addition to stopping drafts, it reduces noise, blocks light, and helps keep dust and odors from entering. Includes hook-and-loop adhesive for secure attachment to doors or windows.
