Over the past few decades, home and business owners around the United States have prioritized upgrading to more effective methods of protecting their families, employees, and properties. State-of-the-art home security systems provide comprehensive protection when used in combination with other measures like locks, cameras, and door security bars.

Here we discuss what security bars do and the security bars we recommend for their effectiveness, ease of use, and best overall value to enhance a home security system.

Why doors should have security bars

Law enforcement agencies agree that all homes should have the security fundamentals. These ideally include monitored home security, durable doors and windows, secure locks on all doors and windows, an adequate alarm system, and a door security bar on each exterior door.

Door jammers are very useful to secure doors. This most straightforward kind of security equipment is easy to use and is available in many configurations that work well on any door. Here are our top selections of door security bars from trusted brands.

1. Master Lock Dual Function Door Security Bar

This durable security bar is an excellent choice for high quality at a low price. This security bar features:

  • Adjustable height from slightly above 27 inches, which fits most standard hinged and sliding doors.

  • Twenty-gauge steel, a pivoting ball joint, and a padded grip prevent the bar’s foot from slipping.

  • Lightweight strength. This bar weighs less than a pound but withstands to 350 pounds of force.

  • A yoke that prevents damage to door handles.

2. Door Jammer Portable Security Device

The Door Jammer device is a lightweight, highly durable, yet compact model. This security bar is excellent for keeping hotel doors, dorm room doors, or other interior doors secure while traveling. Other features of this option include:

  • Fits under doors and conveniently unlocks by pulling upward.

  • Horizontal force converts to vertical force, which pushes the bar down even more securely.

  • Unique system of angles and hinging.

  • Neoprene foot adjusts to extend as needed, with only a 0.3-inch clearance required. Ideal for doors with high thresholds.

NOTE: Requires space (less than a quarter inch) under door, which most interior doors have, but exterior doors normally do not.

3. Brink’s Door Security Bar

The Brink’s security bar is incredibly strong and secure, highly durable, but lightweight. It has:

  • Twenty-gauge steel tube that withstands up to 300 pounds of force.

  • Dual-function security bar for use on conventional doors or sliding glass doors.

  • Adjusts from 25 to 43 inches.

  • Adjustable-length bar and swivel foot for use on various door configurations.

4. Cocoweb PortBlock Dual Function Door Security Bar

For a versatile door jammer, this Cocoweb bar easily adjusts for use on traditional or sliding doors. It’s highly durable and convenient to use. Its features include:

  • Twenty-gauge steel construction that withstands over 350lbs of force.

  • Unique range of 40 height settings, each just ¼ inches apart, for an extra-tight fit.

  • A ball joint that pivots to re-angle the bar for stronger reinforcement.

NOTE: Sold in two packs.

5. Travelers Security Lock

The Travelers Security Lock is a very light but durable door security bar, ideal for travel use. This security bar keeps sleeping quarters safe in hotels and dorm rooms. It has:

  • Aircraft-quality aluminum, which weighs less than one-half pound.

  • Fits most right- and left-hand doors.

  • Fits door frame tightly to prevent crowbar or credit card use for entry.

  • Comes with a leather carrying case that fits in your pocket.

NOTE: Made in the United States, this lock is not for doors with more than a quarter-inch gap between the door and frame. The security lock is only suitable for use on the inside of a door that opens toward the user.

Essential home security measures

Door security jammers are useful to improve your home’s overall security. Other basic security measures that should be used in conjunction with door security bars include:

  • Solid core doors for durability and resistance against breaking in the door.

  • First-quality locks make it more difficult for anyone to pick.

  • Reinforced frame and hinges fortify exterior entry points.

  • Motion sensor lights help discourage criminals from approaching your home.

  • Monitored alarm system serves as a deterrent and alerts you in the event of unauthorized entry.
