Mantrap vs Double Entry Doors: Understanding Access Control Differences


Updated on:

I’m often asked for advice on how to keep buildings and sensitive areas secure. The truth is, it’s not just about digital threats – physical access control is just as important. One common issue that comes up is deciding between mantrap doors and double entry doors. These may seem like small differences, but they can make a big impact on your security. In this article, I’ll explain the differences between mantrap and double entry doors and give you the information you need to make an educated decision. Trust me, it’s important to get this right. As someone who has seen the devastating effects of poor access control, I know that a properly secured building can mean the difference between safety and chaos. So, let’s dive in and explore the two types of access control doors.

What is the difference between a mantrap and a double entry door?

A mantrap is a security access control system that restricts entry to a single person at a time, providing a secure and monitored area. On the other hand, a double entry door is a common design that features two hinged doors that can be opened in either direction. While these terms may seem interchangeable, there are significant differences between them. Let’s take a closer look at the differences between a mantrap and a double entry door.

  • Size: Mantrap doors are typically smaller than standard-sized doors and double doors. They are designed to accommodate a single individual at a time, ensuring that only one person passes through each stage of the entry process.
  • Security: A mantrap provides an additional layer of security, preventing unauthorized access or tailgating. The system ensures that a person cannot walk through a secured door unless authorized and passing through the necessary security measures. Double entry doors, on the other hand, do not provide the same level of security and are often used for convenience.
  • Access control: A mantrap integrates sophisticated access control technology such as biometric readers, keypads, and access cards that verify identity before allowing access. Double entry doors only feature manual locks, and it is up to the individuals using them to ensure that they are properly secured.
  • Usage: Mantraps are commonly found in high-security areas such as military installations, data centers, and government buildings, where access is restricted and monitored. Double entry doors are commonly used in commercial buildings, residences, and public spaces that require easy access and convenience.
  • In conclusion, while both mantrap and double entry doors have similar functions, their designs and purposes differ significantly. Mantrap doors offer higher security and control measures to prevent unauthorized access. Double entry doors are typical designs that are widely used in commercial and residential spaces for convenience. Understanding the differences between these systems is vital in choosing the appropriate security measures depending on the needs of your organization.

    ???? Pro Tips:

    1. Access control: A mantrap consists of two doors with access controls that allow only one person at a time. Double entry doors have two separate doors that can both be accessed at the same time.

    2. Security level: Mantraps are generally considered to be more secure than double entry doors as they provide a higher degree of access control.

    3. Entry and Exit points: Mantraps have a designated entry and exit point that must be followed. Double entry doors do not have this restriction.

    4. Purpose: Mantraps are designed to control the flow of traffic and prevent unauthorized access. Double entry doors are simply used for ease of access and convenience.

    5. Location: Mantraps are typically found in high-security environments such as data centers, banks, and government facilities. Double entry doors are commonly found in public buildings such as malls and hospitals.

    Understanding Mantrap Doors

    A “mantrap” door is a security measure that restricts access to an area. It is essentially a small room or vestibule that is placed in between two doors. The two doors cannot be open at the same time, as the first door must close and lock before the second door will unlock and open. Mantrap doors are mostly seen in high-security buildings, such as data centers or banks. They are designed to prevent unauthorized people from accessing restricted areas, and to control the flow of people entering and leaving a secure space.

    Mantrap doors are smaller than standard-sized doors and often have additional security measures, such as security cameras and metal detectors placed within the mantrap vestibule. Some mantrap doors also require a keycard or biometric authentication to enter. The small size of the mantrap vestibule prevents multiple people from entering or leaving the secured area at one time, which ensures that only authorized personnel is allowed access.

    Defining Double Entry Doors

    A double entry door is simply two doors that are side-by-side and that can be opened simultaneously. These doors range in size and are commonly used in commercial buildings, such as hotels or restaurants, for aesthetics and practical purposes. Double entry doors can be locked, but they are not designed as a security measure.

    Double entry doors are typically larger than mantrap doors, allowing for unrestricted movement of people and larger items. They are often used in high-traffic areas where there are no security concerns, such as entranceways and foyers.

    The Purpose of Mantrap Doors

    The purpose of mantrap doors is to provide a secure entryway to a restricted area, preventing unauthorized access and controlling the flow of traffic in and out of the area. Mantrap doors protect against tailgating, which is the act of an unauthenticated person following an authorized person into a secured area. Mantrap doors are also used to prevent theft, as the small size of the vestibule makes it difficult to carry out stolen items.

    The Purpose of Double Entry Doors

    The purpose of double entry doors is mainly for accessibility and design. They allow for easy movement of people and objects in and out of a building. Double entry doors are often used as the main entrance to buildings, such as hotels or restaurants, as they create a welcoming and grand entrance. They are meant to be inviting and provide unobstructed entry and exit to high-traffic areas.

    The Advantages of Mantrap Doors

    • Enhanced security to prevent unauthorized access
    • Controlled flow of traffic in and out of secure areas
    • Protection against tailgating and theft
    • Additional security features such as metal detectors and cameras
    • Small size of vestibule makes it difficult to carry out stolen items

    The Advantages of Double Entry Doors

    • Easy and unobstructed entry and exit for people and objects
    • Create a grand entrance and welcoming atmosphere
    • Practical use in high-traffic areas, such as lobby areas and entrances
    • Provide accessibility for individuals with disabilities or mobility concerns
    • Larger size allows for easy movement of large objects in and out of a building

    Comparing Mantrap Doors and Double Entry Doors

    There are clear differences between mantrap doors and double entry doors. Mantrap doors are designed for security purposes, while double entry doors are designed for practical use and aesthetics. Mantrap doors are smaller in size and have additional security measures, such as metal detectors and cameras, while double entry doors are larger and unobstructed for easy movement of people and items.

    Mantrap doors are best used in high-security areas with a high risk of unauthorized access, such as data centers and banks. Double entry doors are best suited for grand entrances and areas with high-traffic flow, such as hotels, restaurants, and shopping centers.

    Choosing the Right Door for Increased Security

    Mantrap doors should be used when:

    • Security is the top priority
    • There is a high risk of unauthorized access
    • The protected area contains sensitive information or assets

    Double entry doors should be used when:

    • Accessibility and convenience are a top priority
    • There is no need for a high level of security
    • The building is designed for aesthetics and grand entrances

    In conclusion, it is essential to understand the purpose of each type of door and choose the one that best suits the specific needs of a commercial building. By selecting the appropriate door type, businesses can achieve both aesthetic appeal and security measures to protect their people and assets.
