UL 437
Posted: Tue Dec 18, 2018 7:47 pm
I have seen in UL 437 and in an Australian standard, that there are UL 437 type 1 and type 2 locks. ( https://standardscatalog.ul.com/standar ... dard_437_8 ) Key locks are either just labeled "UL 437" or "UL type 2". I didn't find anything on what type 1 or type 2 is. Does someone here know something?
PS: Combination locks are advertised as "UL Type 1", but I have read that this UL is not 437 but 2000 something. That makes sense, because 437 is for a key lock and not a combination lock.
