Thank you to all who took the time to wish me happy birthday on Monday! One more year until the Big 5-0! (eek!)
I received these photos from Guardian Fire Testing. The bolts have been installed on existing fire-rated doors in a school, and Guardian was asked to relabel these fire door assemblies. Note that the doors already had classroom security locks.
What say you?
In case you’re just tuning in, these bolts do not meet the model code requirements for classroom doors, but these particular doors are in Ohio, where a state code modification allows temporary locking devices if certain criteria are met. All products used as part of a fire door assembly are required to be listed for that purpose, but Guardian is being asked to decide whether non-listed products will negatively impact the performance of the fire door.
