Sturdy and Durable Material: The adjustable doorstop is made of high-quality aluminum alloy, making it durable and ideal for protecting your home and ensuring safety while traveling. Additionally, the non-slip design prevents damage to your floor. (Note: The gap between the door and the floor should be at least 5 to 35 mm.) Safety Protection: The doorstop is easy to carry and can protect your safety whether you are at home or traveling. It uses the principle of physical blocking and, with the double stability of the suction cup at the bottom and the mechanical structure, effectively prevents the door from being opened from the outside, thus providing a strong guarantee of safety protection. Easy to Use: No complicated tools are required, and installation is quick and easy by adjusting the knob. It easily attaches between various types of doors and the floor, and the operating threshold is extremely low. Simply place the doorstop under any door (at home, in a hotel, etc.), and it's ready to use. Remember to slide it firmly under the door when using it. Not suitable for use on very smooth floors. Compact and practical: The adjustable doorstop is small and lightweight, easy to carry, and suitable for inward-opening doors (e.g., hotels) without damaging the floor. Whether you're home alone or traveling, you can take it with you as a safety net. Highly adaptable: The adjustable doorstop can be used as a regular doorstop, and its adjustable design can adapt to the gap between the door and the floor of varying thicknesses. The shock-absorbing and anti-slip rubber design on the bottom increases resistance to the door opening and prevents it from swinging open and closing. It's perfect for use alone at home and in hotels during business trips.
