Fire Door Lock

Ensure building safety and code compliance with our industrial-grade Fire Door Lock. Engineered for fire-rated door assemblies, this hardware provides critical containment during a fire, restricting the spread of smoke and flames while allowing for safe egress.

  • UL 10C Fire-Rated (3-Hour)
  • ANSI/BHMA A156 Grade 1 Certified
  • Heavy-Duty Steel Construction
  • Application: Commercial & Institutional Doors
Overview | Specifications | Applications | Finish Options | How to Measure | Order Checklist

Constructed from high-tensile, heavy-duty steel components, our Fire Door Lock is designed to withstand extreme temperatures and maintain structural integrity during a fire. The internal latching mechanism is engineered for positive latching, ensuring the door remains securely closed under positive pressure conditions as required by UL 10C standards. All components are treated for corrosion resistance to guarantee long-term reliability and performance in high-traffic commercial environments. This industrial-grade hardware is a critical component for passive fire protection systems in Los Angeles buildings.

This fire-rated lock is essential for commercial, industrial, and institutional facilities such as hospitals, schools, offices, and manufacturing plants. It is specified for use on fire doors in stairwells, corridors, and other areas requiring compartmentalization to prevent fire spread. Ideal for both new construction projects and MRO (Maintenance, Repair, and Operations) upgrades, this lock ensures that existing door assemblies meet current fire and life safety codes. It is a vital piece of construction hardware for building owners, facility managers, and contractors.

Specifications

  • Material: Heavy-Duty Steel, Stainless Steel Components
  • Standards: UL 10C, NFPA 80, ANSI/BHMA A156.13 Grade 1

  • Dimensions: Standard backsets (e.g., 2-3/4") for commercial doors
  • Finish: Satin Stainless Steel (US32D/630), Polished Brass (US3/605)
  • Certifications: UL Listed for 3-hour fire rating

Applications

  • Healthcare Facilities: Ensuring patient safety and code compliance in hospitals and clinics.
  • Educational Institutions: Used on classroom, dormitory, and assembly hall fire doors.
  • Industrial Plants: Protecting personnel and assets by compartmentalizing fire hazards.

Target Users

This product is specified by architects, installed by commercial door contractors, and maintained by facility management professionals for MRO supplies and life-safety compliance projects. Bulk fire door lock orders are available from our Los Angeles warehouse.

Finish Options

Our Fire Door Locks are available in industry-standard architectural finishes to match other commercial hardware. Common options include Satin Stainless Steel (US32D/630), which offers excellent durability and corrosion resistance, as well as Polished Brass (US3) for a traditional aesthetic. Contact us for availability of other finishes.

How to Measure

To ensure correct specification, identify the door's required fire rating (e.g., 90-minute, 3-hour), measure the backset (distance from door edge to the center of the lock cylinder), and confirm the door thickness. Also, determine the required function (e.g., storeroom, classroom, passage).

Example: 'Fire Door Lock, 3-Hour UL Rating, 2-3/4" Backset, for 1-3/4" Thick Door, Storeroom Function, Satin Stainless Steel Finish.'

Order Checklist
