2Pcs Spring Door Stoppers, Aluminum Door Stoppers For Bottom, 4.33 Inch Height Product Details ?Durable Material?The door stopper is made of high-quality aluminum alloy, which is rust-proof and durable. The height is 4.33 inches, and the stopper is installed with thickened frosted silicone to ensure a strong support for your door, long and reliable service life. ?Hydraulic Shock Absorbent Technology?Through a lot of testing, the hydraulic shock absorbent can avoid contact with the wall and the door handle, minimize the noise of the door colliding with the door stopper, and bring you a comfortable and serene environment. ?Wide Compatibility?This door stop is suitable for various surfaces. Can be fixed on any uneven surface with screws, such as wood/gypsum board/cement/latex paint-coated walls. Also can use strong self-adhesive stickers to stick on smooth, flat, dry surfaces, such as tile/glass/marble, etc. ?Two-way Easy Installation? Use self-adhesive stickers to install the door stoppers, and you can experience it easily without drilling. Alternatively, you can choose to use screws for a safer, more durable mount on uneven surfaces. We recommend mounting it on a doorknob or on top of a door to keep it safe and out of reach of babies, pets, and household appliances. ?Apartment Essentials Accessories?The matte polished finish adds a touch of sophistication to your apartment and also makes a practical housewarming present for family or friends when paired well with other home accessories.
