A fire-rated mortise lock is an essential component of modern safety hardware, designed to protect lives and property in the event of a fire. Combining durability, high utility, and compliance with industry safety standards, these locks are a preferred choice for commercial, industrial, and even residential spaces. Here's everything you need to know about fire-rated mortise locks, their features, and why partnering with a reliable mortise lock manufacturer, like Keyman, can make all the difference.


Durable, Certified, Fire Rated Mortise Locks

A fire-rated mortise lock is a heavy-duty locking mechanism that is specifically tested and certified to withstand high heat and intense conditions during a fire. Unlike standard locks, these mechanisms are designed to maintain their structural integrity, functionality, and fire-resistance for a specified time, often lasting 20 to 180 minutes as per industry standards.


Equipped with both security and fire safety features, fire-rated mortise locks are ideal for doors that require exceptional durability and compliance with building codes.


Key Features of Fire Rated Mortise Locks

  • Fire Resistance: Tested and certified to meet high fire safety standards, such as UL (Underwriters Laboratories) or ANSI/BHMA.

  • Durability: Engineered with robust materials to ensure functionality even under extreme conditions.

  • Flexibility: Available with customizable options such as lock design, handle styles, and finishes to suit varied architectural needs.

  • Versatile Applications: Can be used for fire-rated steel doors, wooden doors, or any other materials approved for fire-rated systems.

Industry Standards for Fire Rated Mortise Locks

A reputable mortise lock manufacturer adheres to strict guidelines to ensure product reliability and compliance. Keyman design and develop their locks according to industry benchmarks, including:


ANSI/BHMA Standards

ANSI/BHMA (American National Standards Institute/Builders Hardware Manufacturers Association) sets rigorous performance standards for security and durability. Locks that meet these standards ensure consistent and dependable operations in challenging situations.


UL Certification

Underwriters Laboratories (UL) certification assures that the lock has been successfully tested under laboratory fire conditions and will maintain its functionality for a valid period during an actual fire emergency.


Compliance with these standards guarantees that a fire-rated mortise lock is both reliable and safe for use in key applications.


Why Choose a Fire Rated Mortise Lock?

Life Safety

Fire-rated locks prevent the spread of fire by sealing doors shut for an appropriate duration. This crucial feature saves lives, allowing occupants more time to evacuate and reducing the risk of fatalities.


Property Protection

These locks resist the penetration of heat and flames, safeguarding assets and the structural integrity of buildings during emergencies.


Compliance with Building Codes

Installing certified fire-rated mortise locks ensures compliance with legal fire safety requirements, reducing liability risks in the event of an accident.


Seamless Design and Functionality

Fire-rated mortise locks are not just about safety; they also offer sleek, customizable designs that work well with modern architectural aesthetics.

When sourcing fire-rated mortise locks, it's essential to rely on trusted manufacturers who emphasize quality, durability, and compliance. Keyman is a standout name, known for producing high-quality hardware designed to meet stringent industry standards.


Why Keyman Stands Out:

1.ANSI/BHMA and UL Certified: Keyman ensures that their products are designed and developed following ANSI/BHMA and UL standards.

Complementary Hardware for Fire Safety

Fire-rated mortise locks often pair effectively with other fire-rated devices to complete a facility’s fire protection plan. Here are two examples:


1. Fire Rated Rim Exit Device

A fire-rated rim exit device is essential for high-traffic areas like schools, hospitals, and commercial spaces. It offers easy egress during emergencies while maintaining robust fire resistance to match the door’s rating. Keyman’s rim exit devices combine streamlined aesthetics with heavy-duty performance.


2. Vertical Rod Exit Device

For doors that require top & bottom locking mechanisms, a vertical rod exit device is an ideal solution. These are particularly common in double-door applications and provide enhanced security while being fire-rated for compliance.


Both devices are excellent companions to fire-rated mortise locks, ensuring comprehensive safety and security solutions.


Choosing the Right Mortise Lock for Your Needs

With so many options available, choosing the right fire-rated mortise lock may feel overwhelming. Here’s a quick checklist to guide your decision:


  • Certifications and Compliance: Look for ANSI/BHMA and UL certifications.

  • Material and Durability: Ensure the lock is built with high-quality metals and materials.

  • Aesthetic Design: Check for customizable finishes and styles to match your design goals.

  • Intended Application: Evaluate where the lock will be installed—residential, commercial, or industrial spaces.

  • Manufacturer Reputation: Partner with companies like Keyman, known for quality and dependable locks.
