Abstract: A door security device and method for its use. The device includes a winch assembly disposed on a support bracket and with a cover that can be applied to enclose and secure the winch assembly. The device is mounted adjacent a door to be secured. The winch assembly includes a tether, a release lever, and a handle. The release lever provides a one-way ratcheting mechanism to restrict extension of the tether and is operable to release the tether. The handle is operable to retract the tether. A door loop installed on the door provides a secure feature for coupling with the tether. The handle and other safety implements may be stored within the cover. The device is deployable by coupling the tether to the door loop to secure a door against opening even when a door handle or lock on the door have been defeated.
