These restricted child safety friction stay upvc window hinges only allow the window to open a small distance.
A button is pressed on one hinge to release the upvc window the full distance. These hinges are not handed so the hinge with the restrictor button can be fitted where required.
The buttons click back out automatically when the window is closed.
Our 17mm stack height hinges are built up using hinge packers.
Screws are not included but are available separately see
These hinges are sold as a pair, the price is for one pair.
