UL Door Closer Solutions for Fire Rated Doors | YK Fire Door Supplier
YK Door Industry Co., Ltd., a trusted fire door manufacturer and supplier, is proud to offer premium UL-listed commercial door closers designed specifically for integration with fire rated door systems. Engineered for performance and compliance, our door closers enhance the functionality and safety of fire resistance door assemblies in commercial, industrial, and institutional buildings.
Engineered for Fire Safety and Commercial Demands
Our UL commercial industrial door closers feature adjustable spring power sizes (1–4) to accommodate a wide range of door weights and widths. Whether applied to metal fire doors, fire-resistant wood doors, or fire protection doors with UL10C three-hour fire ratings, these closers ensure smooth, secure operation that complies with fire safety codes.
The door closer’s backcheck safety mechanism prevents the door from slamming open, protecting the surrounding structure and extending the lifespan of the fire-rated assembly. This is especially important for high-traffic environments where consistent and controlled closing is essential to maintain the fire-resistant door ratings of stairwell doors, corridor barriers, and compartmentalized exits.
Performance and Compliance You Can Trust
All YK hydraulic door closers are ANSI Grade 1 certified—the highest commercial standard—and ADA compliant, ensuring accessibility while maintaining robust fire protection. Designed for universal application, these non-handed closers support installation on both left- and right-hand doors and offer mounting flexibility (regular, top jamb, or parallel arm configurations).
We utilize rack and pinion operation, backed by a lightweight aluminum alloy body, for durability and dependable performance. Each closer features separate valves to adjust the sweep speed, latch speed, and backcheck force, offering precise control over door motion to suit a wide range of fire-rated door installations.
