necessary to rotate the movable portion of the latch bracket to a vertical
orientation to avoid interference when installing the unit.
TIP For the CENTERLINE 2100 MCC units with arc-resistant door latches, you may
need to tilt the top of the unit slightly to the rear to avoid interference with the
top arc latch bracket. If you do not have enough clearance, you will need to
