DescriptionLARGE DOOR STOPS: Each wedge-shaped door stop measures 12.2 (L) X 5.6 (W) X 3 (H) cm and is best suited for door openings between 1 and 2.8 cm. These rubber door stops are perfect for indoor and outdoor use in the home/office/cabin/garage/school and hospital.WIDE APPLICATIONS: These sturdy, non-slip door stops are suitable for wood, glass and steel doors and they work well on floors such as wood, carpet, concrete, tile, linoleum, stone, asphalt and ceramic, providing superior grip.STRONG: These rubber door stops rely on a sloping design to prevent doors from closing on their own. They fit under most door gaps if you double-stack them, and can withstand daily use without cracking. Reinforced edge around the safety door stops and the improved hollow design that allows for double-stacking make it difficult for these door wedges to tip over.NON-SLIP: Protect your home or office wall with these durable, heavy-duty door stops that won't slip or damage even on industrial doors. Keep your children and babies safe from slamming doors. Pets will not be unable to return home because the door is closed by the wind.
