Andy Mack Posted September 18 Report Share Posted September 18 I understand it a latch bolt must overcome the strike plate, stay in position (positive latching) and opened manually from the inside with a lever/handle and outside with a key or code etc. My concern is that the roller bolt does not automatically lock into position and can move freely. Theres no unlatched test evidence for the door but if the self closing device is able to keep the door closed against the frame is it acceptable?

Neil Ashdown MAFDI Posted September 20 Report Share Posted September 20 Roller bolt type latches are not usually fitted to fire doors. Section 6 of the document 'Code of Practice: Hardware for Fire & Escape Doors' deals with latches and the many fire door related issues concerned with the different types. The document is available online at http://firecode.org.uk/Code_of_Practice_hardware_for_fire_and_escape_doors.pdf Below is particular commentary on Roller Bolt Latches Quote Link to comment Share on other sites More sharing options...
