The Best Door Security Bars and Jammers

When it comes to keeping your home security (be it an apartment or house), a security system is an excellent way to help you gain some peace of mind. But to add an extra layer of difficulty for potential thieves, you might consider an additional safety product to make it very difficult for anyone to enter through your doorway—namely, a door bar (a.k.a a door jammer). These allow you to secure a door from the inside so that it can’t be opened from the outside and can help you feel extra safe at home or when you travel.

Whether you want to use it on a standard hinged door or a sliding one, or even while traveling, there’s a door jammer or stopper bar to keep you and your family safe. We scouted the options to find the best door security bars on the market.

Things to Consider Before Buying a Door Bar or Jammer

  • Door type: Different door jammer options work best on different types of doors. Some models are best for securing a sliding glass door, while others are best for a standard door.
  • Door dimensions: It’s important to make sure your door can work with the door jammer of your choice. Measure the height from the floor to the doorknob, and even the height from the floor to the bottom of your door to be sure it’s compatible with your door jammer’s specs.
  • Placement: Do you want a door jammer that is out of reach of your child? How about a semi-permanent, or portable door jammer? There are so many options and different ways to install them on a door, it’s important to figure out what is ideal for your needs and situation.
  • Installation: Some door jammers install with no tools needed. But if you’re looking for a more permanent option, you may look at the type that screws more permanently to your door or floor.

Summing It Up

When it comes to adding an extra layer of security beyond the traditional deadbolt, a door jammer is one of the simplest and most cost effective ways to do it. Whether you’re in the market for an inexpensive option that installs in a snap, or a more permanent version with a smartphone app, a door stopper will make any home even more safe.

Before you buy, it’s crucial to make sure you factor in the type of door you are looking to secure. There are different options best for standard doors, travel, non-standard door frames, sliding doors and more. Not all door jammer options are created equal, but you can find the perfect one for you at a price that fits just about any budget.
