About door circle lock

Types of circle door locks

The round shape of the door lock is very popular thanks to its simple appearance and convenient operation. Numerous variations exist based on functionality, security level, material composition, and intended use. Here’s a closer look at these types.

Deadbolt circle locks

Circle deadbolt locks add extra protection by inserting a bolt into the door frame when locked. They are generally used with primary entry locks and provide better than average security. Coded or keyed deadbolts rotate the bolt using keys or codes. Single or double cylinder deadbolts have locks on both inside and outside except the sliding part that goes through the glass frame.

Levers and circle locks

These combine the features of a lever handle and a circular lock cylinder. Levers provide easy access by allowing the door to be opened by simply pushing or pulling. Circle levers and locks are suitable for frequent use areas and are popular in commercial settings. They also offer varying security levels from low to high, depending on their intended use.

Circle knob locks

Again, this is a combination of a round lock with a door handle knob. Circle knob locks are for light residential use where security levels are not high. These are great for interior doors, like bathrooms, or in apartments to gain access into. Note that knob locks are easily removed, and this makes them unsuitable for exterior doors where security is paramount.

Circle cam locks

These locks take the form of a circular cam switch and provide very little security. They are designed for securing items like filing cabinets, drawers, and equipment cases. Note that while not offering significant security, they are known for their compact size and easy installation. Their usage is more focused on safeguarding items in restricted areas rather than securing doors.

Smart circle locks

These are the modern devices of a circle lock that incorporates smart technology herein. They allow access via smartphones, biometric scan, or key codes while eliminating traditional keys. Smart circle locks offer convenience, and less worry about lost keys. Some have features like activity logs and remote access for higher security to residential and commercial properties.

Industrial applications of circle door locks

Like mentioned before, circular door locks are valuable in diverse industrial settings. Their application not only enhances physical security but also restricts access to confidential records and spaces. Here are a few ways these locks are used.

Control of access to restricted areas

Circle locks installed or embedded into access control systems strengthen perimeter security. This secures physical perimeters, like fences or gates, restricting unauthorized persons or employees. They can be integrated with electronic access systems, like keycards or biometric readers, providing multi-level security.

Securing valuable equipment and assets

Circle locks protect machines and tools from theft, vandalism, or tampering. They are inexhaustible in warehouses, manufacturing plants, and construction sites where valuable assets need safeguarding. Combined with robust lockout/tagout policies, people can use certain pieces of equipment only after following the established safety procedures to protect workers from harm.

Protecting hazardous areas

In hazardous or explosive environments, such as chemical processing or oil and gas industries, locking doors are vital. They prevent unauthorized access to these areas and reduce the risk of accidents or exposure to dangerous substances. Heavy-duty circular locks are used in these areas and are made of materials that can withstand extreme conditions.

Enhancing data protection in server rooms

With so much advancement in technology nowadays, circular locks are used in securing data centers and server rooms. These ensure that only authorized IT personnel access sensitive equipment and confidential data. Additionally, locking these physical spaces is as important as encrypting digital data for overall information security.

Safeguarding against fire and safety violation

In industrial spaces, the importance of circle locks ensuring safety cannot be overemphasized. They are mounted on fire doors, emergency exits, and safety equipment storage to maintain compliance and protect property. Locks ensure these critical areas remain accessible only to authorized individuals while keeping closed and secured when not in use. This reduces accidents and follows safety regulations.

Product specifications and features

Key specifications for circle locks

  • SPECIFICATIONS: Manufacturers need to be mindful of the following specifications when manufacturing circular locks:
    • Lock grade: This is determined by the Security System of America standards that evaluate lock reliability and resistance to tampering.
    • Backset: The circle lock should be manufactured with several options in order to cater to different door thicknesses and frame types. The backset refers to the distance of the lock from the edge of the door, where both are important for proper installation.
    • Keyway standardization: Using keyway means that the same key operates different locks. For some applications, this is desirable for easy access, while for others, unique keyways per lock are important for added security. Look at keyway designs and the availability of replacement keys when needed.
    • Durability ratings: In assessing the suitability of a circular lock for a given environment, buyers have to consider its ratings. In such cases, pay close attention to the materials used and the wear and tear level of the lock mechanisms when evaluated.
    • Certifications: Speaking of which, look for relevant certifications such as ANSI or ISO. These ensure that circular locks have been certified for employing effective locking mechanisms.

    FEATURES: Here are the important features circular door locks have to offer.

    • Keyless entry: Smart circle locks provide the ease of keyless entry. Put in place with passcodes, biometrics, or smartphones, these eliminate lost or duplicate keys.
    • Anti-picking mechanisms: To improve their security, some circular locks come with anti-picking features, making it difficult to tamper with or unlock by illegal means.
    • Re-keying capability: This feature is important for maintaining security within an area. Some locks come with unlocking features that allow keys to be changed without replacing the lock itself physically.
    • Emergency override: Double cylinder circular locks have an overriding feature where a key or code can allow access even if other methods are blocked.
    • Tamper alerts: Speaking of smart technology, some circular locks have built-in alerts that notify users when tampering is suspected or unauthorized access attempts are made.
