Protect Your Child and Pets: Toddlers are known for their curiosity and lack the ability to protect themselves from dangerous situations. This window safety lock is designed for children and pets, securing hazardous areas like windows, sliding doors, and balconies to prevent falls while playing. Easy to Use: This child safety window restrictor installs with transparent seamless adhesive, preventing damage to furniture surfaces, especially useful where screws cannot be used. The lock design eliminates the need for keys or passwords, providing a better user experience. Adjustable Window Restrictor: Adjust the chain length to control the opening distance based on your pet's size, allowing for ventilation while keeping children and pets safe. The gap size adjusts from 3.5cm to 19cm, allowing for more airflow than traditional window locks. Upgraded Protection: The dual-unlock switch design requires simultaneous button presses to open, easily accessible for adults but difficult for children, providing double protection and allowing for ventilation while preventing accidental openings. Widely Compatible: Made of high-quality ABS material, it withstands temperature exposure, and the stainless steel chain can withstand up to 10kg of weight, ensuring durability.
