Versatile Design for Sliding and Hinged Doors
Whether you use the Security Bar for sliding-door or hinged-door applications, you can rest assured that the bar’s design features are optimized to keep you and your family safe.

For hinged doors, the bar features a pivoting ball joint that keeps it in full contact with the floor, providing a more stable and secure connection. Simply place the padded foot against your floor, and wedge the specially designed non-marring yoke beneath your door handle. The foot will give the bar a tight grip against your floor, and because both the foot and the yoke are padded, your floor and door handle will remain unmarred, even with everyday use.

To secure a sliding door, simply turn the bar on its side, remove the yoke by pulling out the pin, and adjust the bar to the length of your door. Once properly adjusted, the bar will create a firm seating between the door and jamb, ensuring that no one can enter the door from the outside. The Dual Function Security Bar is designed to fit most sliding doors.
