Hello!
I have a Bowater Zenith door which is quite old, it has given sterling service. But, now the locking mechanism is giving problems, it has become very notchy when raising the handle to lock the door. It is also difficult at times to open the door, a similar problem very notchy.
The door has a multipoint locking system.
I have browsed the internet but can't seem to find a replacement part.
Has anyone experienced changing locks on these doors, please?
