How to Barricade a Door that Opens Out

While the majority of doors (particularly front doors) open inwards, outward opening doors are also popular.

An exterior door that opens outward is typically more resistant to force attacks than one that opens inward. However, if you know where the door’s weak points are, you can lock any outward swinging door quickly and easily.

We’ll look at all of the best ways to make your outward-opening door more safe and immune to forced entry attempts in this post.

How to Barricade a Door that Opens Out


The Defcon Products TeacherLock is a bolting lock that you can mount directly on your door. It comes with an inside key (the TeacherLock Activator), as well as the option of inserting an emergency responder key ($50) for unlocking from the outside.

It’s built to require little to no fine motor skills—just click the lock with the activator, and the door will be bolted shut. Simply click the egress push button to open the lock and exit.

The TeacherLock claims to be the only barricade on the market that complies with the International Fire Code. The International Fire Code, on the other hand, is not officially considered the official fire code in all 50 states.

Despite the fact that deactivating the product is a one-step process (pushing the red button), this does not open the door. To open and exit, a second step of pressing down or turning the door handle is needed. As a result, statements of full compliance with fire codes are untrue.

Although the product provides valuable, specific safety instructions for commercial and school buildings, it can can create problems with your state’s fire code.

Drilling and mounting TeacherLock directly to the door is needed for installation. As a result, there’s no guarantee that your fire marshal will approve it, as it’s a post-manufacturing modification that could void the door’s and door jam’s fire warranties.

Finally, the TeacherLock is one of the most expensive barricades on the market, starting at $219. The “outside” key, which allows adults or emergency responders to open from the outside, will set you back an extra $50.

Both an outward and inward opening door can be secured with the Teacherlock. However, plan to pay an extra $20 for inward opening doors.

Bottom line: The TeacherLock is simple to install and secure, but it is not inexpensive, and it may not meet your state’s fire code due to the lack of one motion egress and modifications to an existing fire barrier.


National School Control Systems’ Bearacade Lockdown Response Device is a barricade that slips under the door and is held in place by a pin. It’s tough, compact, and simple to use.

The installation is straightforward, requiring only a single hole in the floor to secure the bolt. Since no permanent mounting is necessary, a fire marshal is more likely to approve it.

The Bearacade is fairly priced at $59, with volume discounts available. In addition, it can be used as an inward-opening door.

The Bearacade Lockdown Response System’s two main drawbacks are that it needs the teacher to open the door to trigger it, placing the teacher and everyone else in the classroom in danger. Despite the fact that it only takes seconds to deploy, an attacker can only need a few seconds to gain entrance or fatally wound a teacher or students.

Another concern is that the construction necessitates floor drilling. To get the perfect match, this installation stage necessitates a high degree of precision.

The Bearacade often necessitates routine maintenance to ensure that the hole does not get clogged with dirt, dust, or other particles that are typical in a classroom or house. The pin will not drop properly if the hole is not visible.

Finally, and most alarmingly, drilling into floors in schools and industrial buildings often reveals asbestos in the tile. Even if the tiles themselves are asbestos-free, some of the adhesives used to adhere the flooring do. Before making any floor changes, always check your school or building’s asbestos file.

Although the Bearacade Lockdown Response System is inexpensive, durable, and simple to use, it is not a secure solution for your school.


The Barracuda DSO is a bar-style door barricade from the BILCO Company that slides over your door handle and rests against the door jam. It is a self-contained unit that does not need permanent installation. It comes in two sizes, one for 36 and the other for 48 “One is for commercial doors, while the other is for 40″-42” doors.

The Barracuda DSO is one of the larger barricades available, but it is lightweight and sturdy.

Although the Barracuda DSO is easy to use, it does enable the user to keep the bar in place while tightening the handle until it is snug. Teachers can find it more difficult to perform these basic tasks while under the extreme pressure of an active shooter scenario.

Furthermore, you may not want to advertise the presence of this product in your room, making finding a place to store the Barracuda DSO difficult.

The Barracuda DSO costs $175.95 on, which is reasonable as compared to other barricades.

So, while the Barracuda DSO is tough and doesn’t need to be installed permanently, it’s a little more costly and not the easiest barricade to set up.


BILCO offers the Barracuda DCS-1 as another barricade option. By sliding over the door closer and immobilizing the door, this barricade works for outward opening doors.

This design makes deployment quick, fast, and secure, taking only seconds to complete. It’s customizable, so you can secure three different door closer sizes: 2.5″, 3″, and 3.5″ “(

The DCS-1 is one of the more affordable choices available, costing $70.95. However, BILCO suggests that the DCS-1 be used in combination with one of their other barricades, such as the DSO (which is specifically stated in their instructions), bringing your total to about $196 per classroom.

The DCS-1’s adjustable parts may also be a source of concern; if the bolts become loose, the DCS-1’s structural integrity can be jeopardized.

The device’s most significant aspect, however, is how few change sizes it supports. According to research, there are TWELVE major door-closer sizes in American schools. About a quarter of those sizes can be accommodated by the DCS-1.

Also, the most critical factor in securing and holding a door shut is a “tight fit” on the door closer. Every quarter inch is important. Applying this product to a door closer that is even a quarter inch smaller than the product’s adjustment amount can mean the difference between properly securing a door and the product firing off the door closer in an emergency.

Minor features like regular quarter-inch rubber on the inside of the product and raised weld joints on the outside edge of the product could cause problems when it comes to sliding the product onto a door closer that is sucked up really close to the door face. These gaps are usually very small, and any obstacle, such as a raised weld joint, may prevent the product from being applied.

In summary, the DCS-1 is inexpensive and simple to set up, but it is only recommended for use in conjunction with another barricade, making it a costly solution.

It has a limited number of adjustment speeds, making it ineffective on 75% of all door closer sizes typically used in offices and colleges. Fitting it into the narrow gaps that often occur on door closers is also challenging due to the many exterior and interior design obstructions.

Finally, the DCS-1 will not operate on a door that opens inward.


Lockdown 1 and Lockdown 2 of the NIGHTLOCK work in a similar way. The attachments are attached to the bottom of the door and lock it to the floor or doorframe.

The Lockdown 1 works by slipping the lock handle into the connection on the door and floor, which uses the floor’s strength to hold the door closed. The Lockdown 2 lock handle fits into the door attachment and wraps around the doorframe in a similar fashion.

Both the lock handles are small enough to fit in a drawer and are simple to install. The Lockdown 1 works for both metal and wood doors, while the Lockdown 2 is only for wood doors.

2nd Lockdown

The Lockdown 1 and Lockdown 2 are both available for $59.95 and $69.95, respectively, making them reasonably priced.

It should be noted that the deployment of each barricade in both Lockdown 1 and Lockdown 2 requires some precision. The instructor may need to align the lock handle with the slot on the barricade to slide it into position, even though fine motor skills are not needed.

This procedure necessitates both time and precision, both of which are scarce in an active shooter scenario.

The Lockdown 1 and Lockdown 2 have the same issue as the TeacherLock in that they require permanent changes to the door, which may or may not be authorized by your fire marshal. The door modifications are post-manufacturing additions that can void the door and door jam’s fire warranties.

Another critical consideration is the expense and duration of the initial installation. According to their installation video, the Nightlock Lockdown 1 and Lockdown 2 require at least a 20-step process per door. There are also several tasks within some phases.

Another concern is that the construction necessitates floor drilling. To get the perfect match, this installation stage necessitates a high degree of precision.

The fact that drilling into floors in schools and commercial buildings often results in problems with asbestos in the tile is especially troubling. Even if the tiles themselves are asbestos-free, some of the adhesives used to adhere the flooring do. Before making any floor changes, always check your school or building’s asbestos file.
