Door security bars, also known as door jammer bars or door reinforcement bars, are devices designed to fortify the security of doors. 

These bars are typically made of sturdy materials such as steel or aluminum and are installed on the interior side of doors. When properly installed, they create an additional layer of protection against forced entry.

Door security bars work by reinforcing the strength of the door and its frame, making it more resistant to break-ins. When an intruder tries to force their way into a door secured with a security bar, the bar distributes the force across a larger surface area. 

This force dispersion helps prevent the door from being kicked in or forced open easily.

Most door security bars are adjustable and can be customized to fit different door sizes. They are typically installed at the base of the door and extend to the floor. 

The bar is positioned against the door and the floor, creating a sturdy barrier reinforcing the door’s integrity.
