Let's call the client Andrey. The old mechanism served for many years, and Andrey decided to install a modern lock. But it turned out:
“The old one was removed, but the new one doesn’t match in size at all.”
This is a common problem with retrofitting old doors.
Why can't you just put any new lock next to it?
Each additional cut:
- changes the design of the canvas;
- may weaken metal;
- complicates finishing;
- creates additional holes.
Therefore, a competent replacement must take into account the existing seat.
What to compare before selection
Meaning:
- body dimensions;
- position of fastenings;
- location of crossbars;
- door thickness;
- existing fittings.
Why the original advice about a specific “Barrier-4” cannot be made universal
The original article recommends a particular older model as a replacement for rack and pinion locks. This may be relevant for a specific door and a specific market, but is not a universal solution for Estonia.
It's better to look for: compatible modern mechanism with minimal door modifications.
What is better to do before purchasing
Don't buy a new lock based on a photo alone. First:
- take measurements;
- determine the design;
- evaluate available modern analogues.
