in the ceiling . fix the mounting corner with tapping screws, washers and dowels .
check tracks horizontality using the builder's level . if required, correct the track's horizontality,
moving the holes in the punched angle bar along the slots of the multi-purpose corner bracket .
leveling of the diagonal a and B is admissible, to do it you have to lift the door leaf up to
the outermost upper position and to check evenness of the clearances between the door leaf
ends and the tracks . Before final fastening of the tracks to the ceiling the spacing between the
opposite angles must be checked (diagonals a and B must be equal) .
