This simple yet effective device provides an additional layer of security to your home, apartment, or office by preventing forced entry and alerting you of any potential intrusion. The door jammer security bar works by securely wedging the bar under the doorknob, making it extremely difficult for someone to push the door open from the outside. However, the added feature of a built-in alarm takes your security to the next level.

The high-sensitive alarm is triggered when someone attempts to force the door open, emitting a loud 120-decibel siren that will alert you and your neighbors of the intrusion. This feature not only deters intruders from attempting to enter your home but also gives you a chance to respond quickly and call for help.

Investing in a door jammer security bar with a built-in alarm is a practical and cost-effective way to enhance the security of your home. By doing so, you can enjoy peace of mind knowing that your property is better protected against potential threats. Additionally, the device is easy to install and does not require any special tools or expertise, making it a convenient solution for securing any type of entryway, including sliding glass doors, patio doors, and even hotel room doors when traveling.

The sensitivity of the alarm is key to its effectiveness, designed to detect even the slightest movement or pressure on the door, ensuring that it is triggered when someone tries to force their way in. This makes it an extremely reliable and effective security device. The low-battery LED light serves as a helpful reminder to replace the batteries before they run out of power, and the 120-decibel alarm is a powerful deterrent that is difficult to ignore, providing a strong deterrent to potential intruders.

Be confident that your patio door, or any other entryway, is secure and protected against potential break-ins and kick-ins when you use a door jammer security bar with a built-in alarm from Guard Dog Security.
