The security industry is a multi-billion dollar a year business. My present invention is a device that can prevent a door from being forced open from the exterior side of the door. A self-installable, easy-to-use device that advances door security. It sets up and operates from the interior side of the door, which makes it inaccessible to lock picking or tampering from the exterior side of the door. I already have a working prototype with 10 functional features, but now need to build the final prototype. I have hired an engineering design company that helped me to re-design the device and prepare it for manufacturing.
