The quick and simple installation requires no tools. The door security bar adjusts in 40 different positions between 27” and 44.5” to fit most doors. It is constructed of 20-gauge heavy-duty steel for extra strength and security. The non-marring top yoke and pivoting padded foot protect your floors, doors, and locks while providing optimal security. This product works best on tile, wood, and concrete floors. The mobile and compact design makes this door security bar great for home, dorm room, travel and more. This comes with a lifetime warranty.

The alarm can be disengaged by flipping the switch on the side.
