In our full recommendation of products we offer our clients the Door Devil Anti Kick plates.

We sell and install these anti door kick plates for your front door, back door, garage door and occasionally a bedroom door, depending on our clients needs.

Why Does My Family Need a Door Devil™?
Alarm Systems and Deadbolts don’t stop violent kicks.

Once the Alarm goes off it’s too late.

They’re already in your house.
If the door frame is destroyed, your Deadbolt is useless.

Most families have no idea this vulnerability exists. Criminals do.
Until that changes, Door-Kick-in’s will remain the #1 method of entry for burglars.

The Door Devil offers 48" solid 16 gauge steel plates that are independently tested to withstand nearly 1,000 foot pounds of force. It works with right or left hung doors and has a tapered design to minimize visibility once installed. This product is proudly made in the U.S.A.
