Window Restrictor Child Safety Locks: 304 Stainless Steel Chain with Dual-Switch Mechanism - Adjustable Window Locks for Baby & Cat Security - Fits UPVC Wooden Metal Sliding Casement Windows - 2Pcs

• UPGRADED DUAL-SWITCH SAFETY MECHANISM: Unlike standard single-button locks that toddlers can easily bypass, this window locks features a spring-loaded dual-switch system requiring simultaneous two-handed operation to unlock. This complex interaction effectively prevents accidental opening by children while ensuring adults can operate it quickly in emergencies, solving the "smart toddler" pain point.
• HIGH-STRENGTH 304 STAINLESS STEEL CONSTRUCTION: Engineered for maximum security, the chain is crafted from premium 304-grade stainless steel that resists corrosion and rust, suitable for humid kitchen or bathroom environments. With a thickened 3mm wire diameter, the safety window restrictor is tested to withstand 15kg to 20kg of pulling force, providing a robust physical barrier against forced entry or heavy pushing.
• PRECISE VENTILATION WITH ADJUSTABLE CONTROL: Solve the dilemma between fresh air and safety. The 18cm to 20cm flexible chain allows you to customize the opening distance, creating a gap between 3.5cm and 18cm. This specific range is calculated to allow adequate airflow while maintaining a gap too narrow for babies or cats to slip through, preventing fall accidents from upper stories.
• UNIVERSAL COMPATIBILITY & DUAL INSTALLATION: Designed to work seamlessly with UPVC, wooden, and metal frames, this window restrictor fits various styles including sliding windows, casement windows, and refrigerator doors. It supports both adhesive mounting for a drill-free setup (ideal for renters) and screw fixation for permanent stability, ensuring the high-quality ABS housing stays firmly in place.
• HOME SECURITY & FALL PREVENTION: Beyond childproofing, this window lock acts as a secondary security layer to deter potential intruders. It creates a secure environment in nurseries, living rooms, and high-rise apartments. By limiting the window opening, it provides peace of mind for parents and pet owners, eliminating the anxiety of leaving windows open for ventilation.
