The bottom sidewall has a first slot and a second slot spaced from the first slot. A first security arm is pivotably mounted to the base plate proximate the first slot. The first security arm is movable in rotation from a first security-arm retracted position, in which the first security arm is within the housing to a first security-arm extended position through and beyond the first slot and in which position the first security arm extends across a portion of the door and reinforces the door when the base plate is attached to the header. A second security arm is pivotably mounted to the base plate proximate the second slot. The second security arm is movable in rotation from a second security-arm retracted position, in which the second security arm is within the housing to a second security-arm extended position through and beyond the second slot and in which position the second security arm extends across another portion of the door and reinforces the door when the base plate is attached to the header. An actuator pivotally is attached to the base plate at a location generally equidistant from and operatively coupled to the first and second security arms. Rotation of the actuator from an actuator first position in which the first and second security arms are in the first and second security-arm retracted positions to an actuator second position rotates the first and security arms from the first and second security-arm retracted positions to the first and second security-arm extended positions.
