These Fire Escape/Egress Friction Stay upvc window Hinges are only suitable for side hung windows (i.e ones with a hinge at the top and bottom of the opening window sash).
With these hinges fitted, when the window opens, instead of the opening sash moving to the centre of the opening, it stays to the side of the window allowing nearly twice as big a gap to escape through.
Built in Easy clean feature allows the window to slide across to the locking side of the frame when fully open so the glass on the outside can be cleaned from inside.
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.
