I am in a bit of a state as were to go setting the door back up The door has a slightly wider gap at the hinge side from halfway down the door Do i have to remove the cover as shown from the inside to get at a adjuster or is it all done by the allen screws that i believe are under the caps , top and bottom I have checked the door corner to corner and it is the same measurement so it must be square Do those little grub screws ,two on each hinge any part of the set up As it is at the moment the door doesnt engage in the lock and shut unless i lift the handle upwards So as you can see i havnt a clue so any help would be a great help Thanks Charles
