The Removable Door Stop, in conjunction with a double swing hinge is an effective solution to overcoming barricade attempts.
During normal use the stop remains locked to the door frame to act as a traditional stop and prevents the door from swinging outward. In the event of a barricade, the removable stop can be unlatched from the frame (using a key) and opened outward, allowing the door to swing away from the barricade.
2100m and 2400mm Stops available in Right or Left Handed configuration. Requires 4mm Key.
