At a time when there is increasing government and local council regulation on building projects and the accompanying architectural hardware - in July 2007, Guardian Lock & Engineering Co. Ltd. successfully fire tested* it's entire range of UK manufactured locks & latches to BS EN 1634-1, for use on 30 minute & 1 hour fire doors.

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 their use on doors of the appropriate construction, and with the appropriate hardware and fittings.

NB:  Where cylinders other than "Imperial" are used, it is specifier’s responsibility to ensure compatibility with lock case.
