1. Robust Door Stopper: Made from quality alloy for durability. The surface treatment through stainless steel wire drawing effectively prevents rust and corrosion, making it suitable for bathrooms and humid outdoor environments. Ideal for both indoor and outdoor use. Durable door stoppers ensure a longer lifespan and provide longterm reliable support for your home. 2. Adjustable Metal Door Stopper: Can be adjusted to fit the height of the door gap (1020mm). The invisible design prevents tripping hazards for children and won't interfere with daily cleaning. 3. Two Installation Methods: The door stopper base comes with doublesided adhesive tape and mounting screws. The adhesive requires no drilling and is suitable for smooth, flat surfaces (not recommended for drywall or uneven surfaces). Alternatively, screws can be used for a permanent installation, offering greater durability and stability. 4. Mechanical Door Stopper: The sturdy mechanical door stopper prevents doors from slamming shut due to wind and avoids sudden closures. It keeps doors open and protects them from hitting adjacent walls. Suitable for bedrooms, bathrooms, offices, and other locations.
