A keeper apparatus engaged to the lower free end swinging corner portion of a gate, not to either of the upper and lower corner portions having the axis on which the gate swings, and not to the upper free end swinging corner portion where the gate has a main latch. The keeper apparatus joins the shortened ends of a horizontal gate support member and a vertical gate support member where, prior to engaging the keeper apparatus on the shortened ends, such intentionally manufactured shortened ends are free and spaced from each other.

A first gate is disposed within a second gate of a barrier for extending across a passageway of a residence. The second gate can be closed to, for example, minimize access of toddlers to the passageway, while the first gate can be opened to, for example, maximize access of small dogs to the passageway. The barrier includes a locking mechanism between the second gate and a frame of the barrier.
