The Best Door Security Bars & Door Jammers

To help you find the ideal door jammer for your needs, we researched top sellers and selected the best door security bars.

A door security bar or door jammer is an effective and simple security solution that helps protect your home from unwanted entry. Door security bars can be used on nearly any door — including residential exterior and interior doors, hotel room doors, and dorm room doors. They are available in a variety of designs, ranging from bars that brace on the floor and hook under the doorknob to small portable devices that function as powerful doorstops.

1. Master Lock Dual-Function Security Bar

The Master Lock Dual-Function Security Bar is an affordable security tool that doesn’t compromise on quality or features. Made with 20-gauge steel, this door jammer includes a pivoting ball joint and padded foot grip that help it stay securely in place. It weighs less than one pound but can withstand up to 350 pounds of force.

The Master Lock can adjust from 27.5 inches to 42 inches, making it perfect for sliding or hinged doors. Securing sliding glass doors is important because they often have weak locking mechanisms that are easy for intruders to defeat. This security bar also features a specially designed non-marring yoke to protect your door handle from damage.

2. DoorJammer Portable Door Security Device

The DoorJammer Portable Door Security Device is a compact, lightweight security device that’s easy and fast to set up. These features make it the perfect solution for travelers who want extra peace of mind, but it can also be used at home. DoorJammer slips under your door and automatically unlocks when you pull it upward. Horizontal force applied to the outside of the door is converted into vertical force that anchors the DoorJammer’s rubberized foot in place.

To use the DoorJammer, there must be a small space (about one-eighth of an inch) between the bottom edge of the door and the floor. Most hotel room doors and interior doors have this space, though some exterior doors don’t.

3. Cocoweb PortBlock Dual-Function Door Security Bar

When it comes to versatility, the Cocoweb PortBlock Dual-Function Door Security Bar stands out from the rest. It can be used on either a traditional hinged door or a sliding glass door. To help ensure a tight fit, this door jamming device offers 40 adjustable height settings that are spaced one-quarter of an inch apart.

In addition to being versatile, this door security bar is also powerful and designed to resist more than 350 pounds of applied force. An added benefit is that this door jammer is sold in a pack of two, allowing you to secure two doors for the price of one.

4. Buddybar Door Jammer

If you’re looking for a well-designed, heavy-duty door jamming product, Buddybar Door Jammer may be what you need. It’s made of 16-gauge powder-coated steel, weighs just over eight pounds, and doesn’t have any plastic parts. Also, its floor pad is eight square inches — which is larger than most bar-style door jammer pads. This oversized floor pad helps keep the bar securely in place and provides greater resistance against outside force.

The Buddybar extends from 36 to 51 inches and can be used on a variety of floor types, including wood, carpet, and tile. Due to its weight, the Buddybar isn’t ideal for traveling, but it’s an excellent door jammer for residential or dormitory use.

5. Travelers Security Lock

Made of aircraft-grade aluminum, the highly effective Travelers Security Lock weighs just 7.3 ounces. It secures the door tightly against the frame to help prevent credit card, crowbar, and lock-bumping entry — all of which are common ways intruders gain access into rooms. It comes with a leather carrying case and is small enough to fit comfortably in your pocket.

The Travelers Security Lock is made in the U.S. and backed by a 30-day, 100% customer satisfaction guarantee. Be aware that this door jammer is not made to secure doors with more than a one-quarter-inch gap between the door and the frame.

Additional Ways to Increase the Security of Your Doors:

Door security bars can be an effective way to help boost the security of exterior, interior, and sliding glass doors — especially when you use them in conjunction with these tips.

  • Strengthen your door’s potential weak points — like door jambs, frames, and hinges — with a door reinforcement device.
  • Mount motion sensor lights near your home’s entry points. In addition to deterring burglars from trying to break in through a door, motion sensor lights also enhance your home’s safety.
  • Install a quality storm door and keep it locked. A storm door makes your home more difficult to break into, and burglars prefer easy targets.

One of these door jamming products is sure to fit your security needs at home or while traveling. If you want to go a step further, take a look at electronic door locks for enhanced home security as well.
