The XFORT Viper Fixed Cable Window Restrictor is designed to enhance safety and security by limiting the opening distance of windows to 100mm, preventing falls and unauthorized access. This makes it ideal for environments where child safety is paramount, such as homes, nurseries, schools, and hotels. It is suitable for all window types, including uPVC, aluminium, wooden, and metal profiles, and can be securely installed with the included multi-substrate fixing screws. The restrictor features a durable 20cm hardened steel cable that exceeds strength test requirements, offering reliable window security. It allows for essential ventilation while maintaining security, ensuring peace of mind, especially in high-rise apartments or upstairs bedrooms.
