High Performance Permanent Restrictor
Engineered to meet the needs of healthcare, hotels and public buildings, the High Performance Permanent Restrictor is designed to withstand sustained and deliberate attempts to force open windows, and is ideal for applications where restrictors are required to comply with and even exceed the requirements of BS EN 14351.
Developed to satisfy the demands of Health Building Note 00-10 Part D, it withstands a static load of 1000 Newtons being applied to a window for 300 seconds, well in excess of British Standard requirements. The restrictor ensures windows cannot be forced beyond a 100mm restriction, or alternatively an opening of 89mm to prevent the passage of small children. Generally fastened with security screws to prevent fastener removal, the High Performance Permanent Restrictor has a space saving telescopic design and is a concealed fixed device which cannot be overridden.
