When a group of concerned police officers saw too much tragedy from normal locks
They invented something new.
They gave it to those in need.
Now, an even better, professionally re-engineered lock can be yours.
It does what a deadbolt, alarm, or 911 often can't do:
It physically stops bad things from happening in the first place.
The Door Bull Stops Them
It's stronger, and it helps your door frame do its job by distributing the force more evenly, and at the appropriate angles.
• Strong - superior-grade, aluminum construction.
• Smart - it spreads force across more of your door frame.
• Handy - store lock on included hanger, or completely out of sight.
• Fitting - works on most (inward-opening) doors as-is.
• Easy - super quick DIY installation on most doors.
