- Strong & Durable: This set includes 2 heavy-duty door stops made from high-quality electroplated metal and durable rubber. Both materials ensure a waterproof and rustproof finish, making them long-lasting for even the heaviest doors. - Non-Slip Adhesion: The door stops feature rubber grippers on both the bottom and top, providing excellent traction. This design prevents the stops from sliding, keeping them securely in place under heavy doors. - Thoughtful Design: Measuring 3 inches (75mm) tall, these door stops incorporate a unique spring design that adjusts height. Unlike typical door stops, this extra height prevents doors from easily sliding over the top, ensuring stability. - Versatile Applications: Ideal for heavy spring-loaded swinging doors, double doors, and various flooring types including parquet, tile, and carpet. These door stops also perform effectively on glass doors, providing reliable functioning in diverse environments. - Performance Assurance: With their solid construction and thoughtful design, these door stops are perfect for both residential and commercial settings, offering the strength necessary for frequent use without compromising on style or functionality.
