A device for restricting movement of a swinging door in a door frame, the door frame having a door soffit extending longitudinally in a first direction from a first longitudinal end of the door soffit to a second longitudinal end of the door soffit, the device comprising: a first door member configured to be fixedly mounted to the swinging door such that the first door member has a first back face that faces toward the door, a first outer face that faces away from the door, a first top face that extends toward the first back face from one end of the first outer face, and a first bottom face that extends toward the first back face from an opposite end of the first outer face, the first door member including a first slot and a first bore, a top of the first slot being open at the first top face, a bottom of the first slot being open at the first bottom face, and the first slot being open at the first outer face, the first slot having a first predetermined shape extending in the first direction parallel to the door soffit, the first bore extending through the first door member and being located in-line with the first slot and proximate to the bottom of the first slot; a connecting member including a first leg and a second leg, the first leg extending in a second direction that is transverse to the first direction, the first leg having a first end and a second end, the second leg extending in a third direction that is transverse to the second direction, the second leg having a third end and a fourth end, the fourth end being fixedly coupled to the second end, the first end having a second predetermined shape configured to mate with the first predetermined shape to permit the first end to slide into the first slot through the first top face such that the first leg extends through the first outer face and the third end overlaps with the door soffit thereby preventing rotation of the swinging door; and a fastener having a first portion and a second portion coupled to the first portion, wherein when the fastener is in a first position relative to the first door member, the first portion of the fastener extends into the first bore and the second portion of the fastener supports the connecting member in the first slot and blocks the connecting member from exiting the first slot through the first bottom face; wherein when the fastener is in a second position, the second portion of the fastener does not block the first slot and the connecting member is permitted to drop out of the first slot through the first bottom face, wherein the the fastener includes a threaded member and a head that engages a side of the door that is opposite the first door member, wherein the second portion of the fastener is a section of the threaded member. a first door member configured to be fixedly mounted to the swinging door such that the first door member has a first back face that faces toward the door, a first outer face that faces away from the door, a first top face that extends toward the first back face from one end of the first outer face, and a first bottom face that extends toward the first back face from an opposite end of the first outer face, the first door member including a first slot and a first bore, a top of the first slot being open at the first top face, a bottom of the first slot being open at the first bottom face, and the first slot being open at the first outer face, the first slot having a first predetermined shape extending in the first direction parallel to the door soffit, the first bore extending through the first door member and being located in-line with the first slot and proximate to the bottom of the first slot; a connecting member including a first leg and a second leg, the first leg extending in a second direction that is transverse to the first direction, the first leg having a first end and a second end, the second leg extending in a third direction that is transverse to the second direction, the second leg having a third end and a fourth end, the fourth end being fixedly coupled to the second end, the first end having a second predetermined shape configured to mate with the first predetermined shape to permit the first end to slide into the first slot through the first top face such that the first leg extends through the first outer face and the third end overlaps with the door soffit thereby preventing rotation of the swinging door; and a fastener having a first portion and a second portion coupled to the first portion, wherein when the fastener is in a first position relative to the first door member, the first portion of the fastener extends into the first bore and the second portion of the fastener supports the connecting member in the first slot and blocks the connecting member from exiting the first slot through the first bottom face; wherein when the fastener is in a second position, the second portion of the fastener does not block the first slot and the connecting member is permitted to drop out of the first slot through the first bottom face, wherein the the fastener includes a threaded member and a head that engages a side of the door that is opposite the first door member, wherein the second portion of the fastener is a section of the threaded member.
