Abstract
To open a two-action gate, a sliding of a latch and a lifting of the gate to disengage a double stop is required. Performing one step without the other fails to open the gate. The gate is engaged in a frame which may in turn be engaged in a partition or doorway. Via a thumb tab, a portion of the latch can be slid out of the frame. Then the gate is lifted to lift the double stop up and clear of a lower portion of the frame such the gate is swingable. The gate is journaled to a vertically running frame member which serves as the swinging and sliding axis for the gate.
