What is needed to install The Door Bull?
Typically, a drill with a normal Phillips head driver is sufficient. We provide the drill bit for drilling pilot holes. In some cases, if the door fits tightly in the frame, a chisel may be needed to create a shallow depression for the plate.
What is the drill bit for?
The drill bit is used to drill pilot holes for the screw. It is essential to drill pilot holes before screwing in the screws for proper installation.
Will criminals try to break through a window instead?
Statistically, intruders prefer to break in through doors for silent and easy entry. The Door Bull prevents them from opening your doors, making your house not worth the effort. Breaking a window would be loud and also dangerous for criminals breaking in.
Why is The Door Bull so effective?
Our patented design reinforces your door using the strength of the frame, preventing anyone from kicking down the door. This impedes intruders and also forces them to switch to a louder route, which is statistically less appealing.
