Hi!
I'm trying to fit a new horizontal mortise lock into an internal door.
The hole in the door is about 0.5cm too tall for the new lock!
What is the best way to work around this? I was thinking about finding a slim piece of wood, maybe hardboard, and cut it down to size, and glue it to the top of the hole (so the new lock aligns better with the door-handle holes) with wood glue.
Is this method ok? Or is there a better solution?
Thanks!
