FM can do whatever they want but no where that I know of are they the legal standard. Perhaps you said that in your 3rd paragraph but where would FM exceed 13 but only need 2" lines vs. 2.5"? Do you mean to say FM has a higher density than 13 but rounding mathematically you get 2" lines and when you recalc per 13's lower density and rounding up you end up with 2" lines? Does this actually happen? Is this just a marketing trick by FM seeming to require a higher level of protection but in reality it's the same? Cynical I guess. Chris Cahill, P.E.
