INSTALLATION VIDEOS ARE IMPORTANT: The working principle of this product is unique. Please refer to the installation video before use. The video is split into two segments: one showing screw installation, and the other showing adhesive installation.
ADJUSTABLE HEIGHT: This door stopper is designed for door gaps between 5mm and 25mm ( 0.2" 1"). It can be adjusted within this range to fit different door sizes. Performance may vary if the door gap is outside this range.
TIPS: Adhesive installation can be used on suitable smooth and stable surfaces, avoiding rough or unstable areas. Screws are available as an alternative fixing method if adhesive is not suitable. For low-temperature environments (below 50°F), warming the adhesive surface can help improve bonding performance. Full adhesion strength is achieved after approximately 72 hours.
DURABLE DESIGN: Made of heavy-duty zinc alloy with soft shock-absorbing materials for quiet operation. The electroplated surface is scratch-resistant and designed for long-term use. The ultra-thin base helps maintain a clean floor surface without obstruction.
VERSATILE USE: Suitable for common indoor surfaces such as tile, wood, and laminate with proper installation. Ideal for bedrooms, living rooms, kitchens, and offices
