I need to replace the 1930s sash locks in a couple of Crittall patio doors, but I can't find anything suitable. Can anyone help?
The lock slides into a metal pocket so needs to be no more than 16mm thick by 102mm high. Setback is 67mm.
If I could find a euro lock case I'd be happy to cut a suitable opening in the door for the lock barrel but the setback needs to be right (or close) because I can't move the handles.
