The door stopper can firmly fix the opened door, avoiding the door handle from hitting the wall, skirting board or nearby furniture, effectively reducing scratches, dents and paint peeling, and extending the service life. When carrying items or pushing or pulling heavy objects with both hands, the door is firmly held and will not automatically close. Doorstops protect your walls and doors. Suitable for a variety of surfaces, including tile, wood, and composite panels, they are an essential addition to your home. This doorstop is made of high-strength zinc alloy and uses soft, shock-absorbing material for quiet operation. The electroplated surface is scratch-resistant, ensuring durability. The ultra-thin base leaves no cleaning dead spots or obstructs pedestrian traffic, keeping the environment clean and safe. This doorstop is designed for doors with gaps between 5 mm and 25 mm (0.2 inches to 1 inch). It is easily adjustable to accommodate various door sizes within this range. Please note: If your door gap exceeds this range, it will not work properly. You can use adhesive to attach the doorstop (but avoid using it on unstable walls or floors) to avoid drilling holes in the wall. If the installation area is not suitable for adhesive, screws can also be used for securing it. When using adhesive for installation, if the indoor temperature is below 50°F (approximately 10°C), heat the adhesive with a hairdryer before use to ensure a stronger bond (bonding strength reaches its peak 72 hours after installation)., Manufacturer: WLH Alexanders
