I need to find a certifire rated tubular latch for an FD30 firedoor with maximum dimensions somewhat less than pretty much everywhere I can search online has.
Max depth <64mm - that's OK.
But max size of casing 19x15mm?? Most seem to be 21mm+
And the forend can't be larger than 57x26mm - again this is a few mm less than what I've found.
