The coupling bumper is selectively moved relative to the pivot axis into an alignment position where the coupling bumper is positioned to cooperate with a door coupler. At least one stationary support is situated to contact the coupling bumper when the latch is in the released position where the stationary support bears a load associated with moving an associated door.
