Meet The Door Bull: Built by Cops, Trusted by Thousands
After seeing too many break-ins up close, a team of police officers created something better: a smarter, stronger way to lock your door.
The result? The Door Bull. A professionally engineered device that uses your door frame to block forced entry—where deadbolts often fail.
No alarms. No apps. Just pure, physical protection. Simple to use. Nearly impossible to break through.
Take control of your home security—before you need to.
How It Works:
Stop intruders before they ever get in.
The Door Bull installs between your door and frame, instantly reinforcing your home’s most vulnerable point.
Deadbolts focus all the force on a tiny spot. The Door Bull spreads it out—making your door up to 100x harder to break through.
Most break-ins happen fast. Kicking in a deadbolt takes 8 seconds. The Door Bull makes it nearly impossible.
Intruders go for the hinges next. That’s why we include 6 heavy-duty screws to reinforce them too.
Engineered for real security.
Built to hold when it matters most.
