All you need to know about door security devices
Door security bars, reinforcements, and deadbolts are quite similar and serve the same purpose. However, there are small yet significant differences between them, knowing which will help you choose the store’s right device.
Lock Reinforcer
These devices usually have to go on your existing lock and are great to turn away lock-pickers and occasional burglars. Highest quality reinforcers also prevent tampering and resist pressure. Besides, these devices are usually easily transportable and perfect for traveling. If you have a smart lock, make sure that it is compatible with it before buying any.
Jammers
These devices are meant to stop the doors from opening to prevent break-ins. One end of a jammer has to sit firmly on the floor, and the other end should be near the knob. The majority of these devices are pressure-mounted and can withhold hundreds of pounds of pressure.
Safety Bars
Safety frames are usually placed in the middle across the door frame. They work best with sliding doors and are perfect for patios.
Things to consider before securing your door
There are quite a few quality door securing devices on the market. However, it might be tricky to pick the right one for your household, having so many options. Here are the most important things to pay attention to.
1. Measurements
Every house and doorway is different, so make sure you know the dimensions of yours. It is crucial because if it doesn’t fit well, a deadbolt or jammer will not work. A standard doorway’s width is usually between 30 to 36 inches, while the height is harder to guess. It can go up to 80 inches. Measure your doorway before the purchase!
2. Base, middle, or top?
Devices currently available at the market can be installed at the base of your door, in the middle, or high up. Each one has its pros and cons, so be sure to study them to select the right one for you.
3. Materials & Sturdiness
While most security devices are made of aluminum, steel, or other metals, some have plastic details that are more fragile. Some devices also come in different colors to fit the interior of your house in the best way.
4. Installation & Design
A door security device setup is usually quite simple, but some products might require you to use some tools and drill. Just keep that in mind as installation can potentially add time and cost to the price of the device itself.
5. Adjustability
Some security devices make it possible for clients to adjust the height or width of a device, which can be very handy if you plan to use the same device on different doors, for example, at home and when traveling.
6. Pricing
The price, of course, is one of the most critical factors. While there are great inexpensive devices out there, the cost of quality products that can withhold strong force is usually higher. If you have the resources, home security is worth investing in, as dealing with a burglary’s consequences will be a lot more expensive.
Helpful tips for new buyers
A security bar is something that provides an extra layer of protection for your household. However, there are basic things that decrease help secure your home.
1. Always Lock Up
Locking up is extremely important even if you live in an area considered secure. Don’t make it easy for thieves to enter your house. Ensure all locks work properly and, if necessary, get a deadbolt, a surveillance camera, or another security device.
2. Pay attention to your windows
Burglars don’t always get in through doors. Large windows are an easy getaway into a house. A glass break or entry sensor is a great solution, but if you are not ready to invest in those, make sure that at least you have durable curtains that prevent passers-by from seeing what’s inside your house.
3. Add protection to Sliding Doors
It is vital to secure all doors, sliding patio, and balcony doors included. Those large glass doors are especially susceptive to break-ins. Some tools you can reinforce them with include polycarbonate coating, thick pane, or a security bar.
4. Deadbolts are great
Deadbolts are simple, easy to install, yet handy when it comes to house security. Spring-loaded, sturdy, and easily unlocked from the inside, they work great during emergencies as well as day-to-day security.
5. Security Door is a Must-Have for Every Household
If you value your safety and your possessions’ security, a security mechanism is a great investment to make sure your house is protected. Fortunately, there are plenty of devices on the market to choose from. To make the selection process easier, we created this list of 2021 top security devices.
