Traditional Bespoke Cam Catches 
Cam catches are a weak point on a sash window and were easily opened by unwelcome visitors. Bygone have specially developed solid locking catches, secured directly into steel reinforcing within the sash. 
Limit Stops 
Limit stops are devices that prevent a window being opened beyond  
100mm initially,

Continuous Horns 
Bygone sash windows have integrated continuous horns, which are so essential  
to achieving a truly authentic  
sash window appearance. 
Authentic Georgian Bar 
Bygone windows have triple fastened (for strength) internal & external Georgian bars, which give a high quality authentic look. 
Most “cheap” replacement sash windows have Georgian “canes” placed in between two sheets of glass. This makes it obvious at a glance that your home has cheap double- glazed sash replacements as they do not have the depth, character and shadow lines which make sash windows with Georgian bars look so good.
