A U-shaped apparatus comprised of a tube with a hook on one end which can be actuated from the other end. The device is used to manipulate the lever mechanism of a locked door from outside of the locked room by sliding said device underneath a door, guiding the device into a position where the hook is above the door lever and pulling on a cable from the other end of the device. The cable being pulled causes the hook to descend grabbing the door lever, pulling it downward and releasing the lock mechanism. The use of the device allows for access to locked rooms when electronic locking devices fail or master keys are unavailable and access to locked rooms becomes necessary. |
