Door Armor is a home and property security brand from Armor Concepts, specializing in patented steel reinforcement systems for existing doors. Founded in 2004, the company says its products have helped secure more than 500,000 doors and have been tested and recommended by police. Door Armor kits use galvanized steel components attached to a door and its frame to reinforce vulnerable points against kick-ins and prying, helping stop forced entry before an intruder gets inside.

Designed for do-it-yourself installation, most kits can be fitted with a drill in under 30 minutes, without removing the door from its hinges. The components are available in several colors to coordinate with lock hardware and are designed to be barely visible once installed. Door Armor offers solutions for exterior, interior, outswing, sliding glass, and mobile home doors, along with window security products, accessories, and bundles. Its MAX and MINI kits include a lifetime kick-in guarantee of up to $500 and $300, respectively. The brand also provides installation videos, customer support, and security information.
