The company took this step to help architectural hardware specifier's & suppliers whilst scheduling, as they can have confidence that choosing any of Guardian's UK manufactured locks & latches will allow them conform to fire safety regulations*. 

*Subject to there use on doors of the appropriate construction, and with the appropriate hardware and fittings.
