The at least one keeper arm has a latch portion and is mounted on the housing. The at least one keeper arm is movable between a closed position, where the opening is occluded by the latch portion, and an open position, where the door latch may be released from the opening. The latch portion may include a bifurcated member having inside and outside legs arranged in spaced parallel relation so as to define a gap therebetween. The gap is configured to receive a latch plate of an interlocking latch mechanism when the at least one keeper arm is in the closed position.
