What is a door security bar?
A door security bar is a metal tube that braces against the doorknob and the floor. It’s easily adjustable for a variety of lengths. The door security bar is simple to set up and works with all kinds of doors.
How do burglars get in?
Door security bars work as extra security for your front and back doors because that’s how burglars often enter the home. Home invasions are a scary part of daily life.
How do you stop a break in?
The best way to stop a break in is to have security measures in place. Cameras and an alarm system can alert you to dangers, but you need more protection than that. You need a system that is going to prevent a break in – not just record the burglar trying to gain access.
It’s important that you don’t have carpet on the floor, though. That can make it easier for a thief to push it aside.
Do burglar bars work?
It’s not a bar, but it’s the same concept.
How can I make my door more secure?
With a security bar, you can make your door more secure. There are other things you can do to make the entrance to your home secure from those who would do you harm.
First, you can buy a solid door. One with a solid core can’t be broken in the middle. It wouldn’t make sense to bar the door if the thief could kick a hole in the middle of the door itself.
Second, you could reinforce the door frame. When someone kicks the door, it’s the frame that can fail. The door frame can fall apart, which gives the burglar access. The includes both sides of the frame.
Make sure you’re reinforcing and bolstering security on all your first floor doors. That includes the one from the garage.
Lastly, use outdoor lights on a motion sensor. That will alert you to someone coming near your home. You’ll be aware before anything happens. It can often be enough to turn a burglar away from exposing himself.
How can I make my apartment door more secure?
It’s harder to secure your apartment door when you might not be allowed to make changes. There are still things you can do, though. Start with the door’s deadbolt lock. It’s likely a flimsy lock that the last tenant might even have keys to.
If you have sliding glass doors, you can use a security door bar on them to keep them from opening. Find out if your lease allows you to make changes to the lock on the sliding glass door and change it out for a better one.
How do I protect my home from intruders?
Alarming your windows and doors is a good place to start. When you’re not home, this will protect your home from intruders. You can also get one that alerts you to other emergencies like fire or carbon monoxide.
Criminals want an easy score. When you make it more difficult, they’ll move on from your home to someone else’s home. It’s unfortunate, but they’ll target a home with more vulnerabilities.
Make sure the outside of the home is illuminated with motion detecting lights. That will often encourage burglars to move on before they’ve even attempted to enter your home.
Keep your doors locked and use a security bar to block all the downstairs doors. That will include the back door and the one to the garage. The garage should have a security feature, too. Windows should be shut and alarmed at night as well.
It can help to get a guard dog for the family, too. Any dog that barks can be a security dog that will send a thief scurrying off into the night.
Burglar Break-In Mentality
The most important thing for homeowners is to feel safe in their own home. But home safety doesn’t take care of itself – you have to play a pro-active role in the process.
Meanwhile, burglars are out there and they might just pay you a visit – ready or not.
The act of robbery isn’t exactly Mission Impossible. Break-in methods are usually not sophisticated. It usually happens quickly, sloppily, and involves brute force.
After all, they’re not called “break-ins” for nothing.
It’s worth noting that, on average, burglars aren’t usually too bright. That’s why they’ll try what’s easiest method first, which is simply to test to see if you locked your door.
If not, they can just walk right in.
If you do lock your door, as you should, a burglar will likely try their next big move – kick the door down.
The Importance of a Good Deadbolt Lock
This is where your deadbolt comes in, if you have one installed.
If your door lacks a deadbolt, and only uses a latch bolt (the one with the angled edge), that relatively small latch bolt is the only bolt standing in the way of a criminal and the inside of your house.
(*don’t worry, we’ll get to security bars soon enough – it all ties together!)
We say a latch bolt isn’t enough. It would be better if you used both a deadbolt and a latch bolt together, as shown below.
Many doors have deadbolts installed, but some don’t. It’s not always necessary to install a deadbolt, but we think it is if you have anything worth protecting.
The effectiveness of your deadbolt depends on a few factors, with perhaps the main factor being the “throw” distance of the deadbolt.
In other words, is it a long deadbolt or a short one?
The strike plate and door jamb are two important parts of your door you should know about, because this is where your deadbolt will extend into and hold it in place.
If the strike plate or door jamb is weak, or the hole where the bolt inserts is shallow, these are weak points in your doors’ security.
The image below has a deadbolt and a latch bolt engaged. A quality deadbolt adds another level of protection against break-ins, especially if it reaches 2″ into your door jamb.
Security Bars / Door Jammers and How They Work
For some, a deadbolt is enough to make you feel safe in your home. It adds more protection against break ins than just using a latch bolt.
Some people, however, want all the security they can get, and that’s where security bars and door jammers come in.
Security bars add a different kind of protection to your door, which can be used in addition to deadbolts.
How a security bar (also called a door jammer) operates is based on simple physics, and it’s a concept that is worth understanding fully.
Think of it this way. Any kind of deadbolt, no matter how strong it is, is still extending its force into the door sideways, or on the same plane as the door.
That’s all well and good, but when someone tries to break down your door, the force is coming from a perpendicular direction.
This is an important point to understand, because an effective security bar / door jammer is using its own strength to absorb the force as it hits the door and shift it vertically into the ground. In other words, perpendicular to the door itself.
Here’s a drawing to illustrate this point (not the best at drawing, but hopefully you get the idea).
Here is another illustration by a company called DoorJammer, showing how their product works using the same physics.
Keeping this in mind, watch this criminal as he kicks his way into a residence.
Imagine there was a security bar on the other side of that door instead of nothing. The force of his kick would have gone into that security bar and the door would have held strong, most likely.
This is because, in this case, the bolt or bolts holding the door closed didn’t do their job. A door jammer or security bar would certainly have lessened the chance that his one single kick to the door would not have opened it.
Now watch this next criminal try the same thing, but this time, he doesn’t get inside. He does, however, use both his feet and shoulder weight to try and break in to the residence, as burglars often do.
Notice how this criminal wasted no time in attempting to break down the door. Criminals are in a hurry because if anyone saw them doing this, they would probably call the cops. They only have a few seconds to try to bash through your door and into your house.
So, what kept this criminal out? We can’t say it was a security bar for sure, but it would make sense if it was a security bar helping to keep him out, because it works based on the physics we described earlier.
When someone tries to put their weight on a door to break it open, the security bar is there to absorb some of their weight, making it much, much harder for that brute force tactic to work on a door.
Security Bar / Door Jammers – A Closer Look
Ok, so we’ve already discussed basically the idea behind how a door jammer AKA security bar works, but what exactly is this device? Let’s take a closer look.
First of all, it’s worth noting there are all sorts of different security bars AKA door jammers out there.
We don’t just mean in terms of brands and sizes, but also in terms of what kind of doors you can use them on.
For instance, you can also use them for sliding doors, like this one:
Keep in mind, this one seen above is the same type that can be used for a regular door, except someone just laid it down so it fit in that space and makes it impossible for a burglar to exert enough force to break or remove the security bar that blocks their way.
For sliding doors, people will often use a piece of wood to do the same thing as the bar will do, except the bar is designed to stay in place a lot better.
Generally, a security bar is just long piece of steel or iron with a little grabber on one end where it grabs your door handle and a foot on the bottom.
Popular models of this kind are made by Brinks, Master Lock, Securityman, and Ideal Security Inc.
There is also the DoorJammer, which looks like this, but functions in a similar fashion.
Most of these door jammers (including THE DoorJammer) have things like adjustable bases and some part that grabs onto the door. In the case of the DoorJammer, the part that grabs the door is at the bottom.
There is also the kind of security bars specifically used for sliding doors, and which lie horizontally, like this:
The security bars reviewed in this article are rather hefty, due to being made of metal (steel, iron), and are designed to do their job with optimal efficiency.
The security bars we will be talking about can be ratcheted into place for a snug fit, to ensure their stability and effectiveness.
Once again, to put it plainly, door jammers have one express purpose – to keep someone out of your house.
