Adjustment on folding patio doors

[Jever]

Afternoon all,

I had a set of bi-fold patio doors installed about ten years ago (see pics attached), which have worked well ever since.

However, over the past couple of years, the main access door (on the right from the outside) has dropped a bit and nudges the rubbers out when I open or close it.

I've been looking for where I might be able to adjust the doors but can't seem to find anything. Having watched a few youtube videos, there is sometimes adjustment on the door hinges with an allen key but that doesn't seem to be the case with mine (see second photo attached, I've photographed the top of one of the hinges).

I'm convinced there must be a way of adjusting them, as you'd need to be able to do it when installing, surely?

Is it just a case of screwing the left hand top further back into the wall to pull the bottom right upwards or am I missing something?

Grateful for any tips

Jever

Hinge adjustment isn't what's required here, the door needs toe and heeling, a process used to square the door up by using the glass
