What is a Door Security Bar?

When considering overall home security it is important to first cover the basics. Most criminals look for homes with poor lighting and unlocked doors. A door security bar is a special security device that is placed behind the door. This bar adds additional reinforcement to door locks and deadbolt locks by strengthening the complete door frame area.
Most sliding glass doors use a door security bar as an added security device. This bar prevents the door from opening by causing a jam in the sliding area. The sliding glass bar comes in many sizes but is typically made from metal. These bars latch securely between the two doors and the slider.

Door security bars have been used for centuries. In ancient times large wooden bars were used to secure the doors from unwanted entry. This form of wooden restraint made it nearly impossible for attackers to break down the large gates of a castle entrance.

Some bank safes include a door security bar design. These bars are typically made from large steel beams that bolt a door securely into the door frame. This bar causes the disbursement of frame support to surround the entire door area. The security bar uses a design that moves the door breaking points away from the door locks.

Some door security bars are wedged between the door and floor. This type of security implementation is similar to wedging a jamming device under a door knob. The door wedge implementation is less attractive then a standard door bar, but provides additional security not available with a deadbolt or door lock alone.

A door security bar can also be integrated into an advanced alarm system. This type of implementation requires additional sensors to be placed on the door jams. When the alarm is armed, the door sensor will activate the security features of the alarm system once the door is opened.

Most electronic doors use a door security bar feature. These doors automatically open and move the security bar into place after an individual walks into a secure building. Having an automatic security bar ensures the bar is always kept in a locked position.
An automatic gate is a luxury feature that is typically found in expensive homes or neighborhoods. These gates are opened with remote sensor devices. Many gates include door security bars. These bars are automatically inserted between the two gates, which prevents them from opening.
