The construction remains
that had been knocked out
along with the lock
had to be torn out of the inner door.
They were completely sawed out
and a fresh piece of timber
was installed instead. The bar
could be glued to it hence the door
is wooden. There was no desire
to get new locking mechanism.
On the contrary, there was an idea
to get rid of them in every
other room, at least of those
that can be closed
from the inside. The oblong socket
was drilled into restored door
and then stuffed with a regular
roller latch. Installing the door skin
completed it's look.
Strike plate on the jamb
remained the same, it was approximately
the size of the
roller (only slightly deeper).
