I would like to install security screens on my casement windows in an old Federation style house.
I was advise by the installer for this to work, I would have to replace the current window lock and casement stay to a window winder.
I thought the Whiteco window winder might suit this purpose.
however, another tradesman advise that as some of the casement windows are hinged on the right side and the others hinged on the left side, I would have to look for window winders that are left/right hinge. Could anybody advise if the Whiteco would work or where can I get this type of window winders?
Thank you.
