Types Of Window Hinges

...

The Arkay Restrictor Hinge has a unique patented mechanism that restricts the initial window opening to 100mm in compliance with BS8213, Part 1: 1991 'Code of Practice for safety in use and in Cleaning'. Designed to be unobtrusive, the opening catch is less tempting to children. The mechanism requires a certain level of strength and dexterity to operate and two hands are required to coordinate opening, giving added protection.

An automatic reset facility ensures safe operation at all times. Side hung windows can be 'locked' open, making cleaning safer and preventing the window from being blown shut. The entire restrictor mechanism is integral to the hinge, eliminating the need for a separate restrictor.
