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?

Classroom Surface Bolt

Classroom Bolt 1

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.
