On a fire-rated exterior door, the hardware including latching force may not exceed how many pounds?

In the context of fire-rated exterior doors, the latching force is critical for ensuring that the door functions properly in the event of a fire. The standard for latching force specifically denotes that it should not exceed 15 pounds. This limitation is put in place to ensure that in an emergency, doors can be easily operated by occupants who may be panicking or in need of immediate escape.

By adhering to this weight limit, manufacturers can design locking hardware that balances security with ease of operation. This aspect is crucial because, in emergencies, even a slight excess in required force could hinder a person’s ability to exit quickly, compromising safety.

Understanding this standard helps contractors and builders ensure compliance with fire safety regulations, which ultimately protects lives and property.
