Abstract: A collapsible gate may provide a temporary barrier to prevent movement between rooms, or to prevent access to a staircase, in a home or commercial building. The collapsible gate may be secured to framing material within a wall and adapted for storage within a wall cavity, such as a pocket door frame, when not in use. The collapsible gate may be vertically retractable and adapted to fit between two framing studs to stow within a wall cavity and out of sight. The collapsible gate may include a counterbalance to maintain the gate within the wall cavity when the gate is in the fully open position, and to assist in opening the gate when the gate is lifted from a closed position.
