The Door Bull is a security device that you place on your door to distribute the force more evenly in the event of a forced entry. Deadbolts fail quickly within one to three kicks and not as reliable as you think. If you are not a fan of door bars, this is a great option. Made of superior-grade aluminum, it is easy to install on most inward opening doors. The Door Bull includes all of the hardware (the lock, frame plate, handy hanger, heavy-duty screws, and drill bit) needed for installation. All you have to do is install the frame plate securely onto the frame of your door and hang the Door Bull lock on top of it and you’re done. When not in use, you can hang the lock on the handy hanger.
