What is a home security bar or Door Jammer?

A door security bar, or Door Jammer, is a portable and adjustable device used to reinforce the security of a door. To use this tool, you can either lay the bar down in the space between a door and the wall, or you can prop it under the door knob with the rubber bottom against the floor. Either way, it will prevent a sliding door or traditional door from opening when it is used. 

This multifunctional tool can be used in your home, or other properties like hotel rooms or businesses. Made with heavy-duty 20-gauge steel, our Door Jammer adds extra security to a locked door and prevents someone from entering.Â
