Span of ww-truss

What is the span of a ww truss (not the usual w-truss) at a 19-degree pitch, snow load zone 1.5, and 45x120 in the upper and lower chords?

Does it really apply for the ww-truss? It's not much different from the w-truss if you look here: https://www.traguiden.se/konstruktion/dimensionering/hjalpmedel---tabeller/

ww truss is not a clearly defined concept. With the given assumptions, it will only be guesses. According to the wood guide, w trusses can handle both 14 and 27 degree roof pitches with the same dimensions on the top and bottom chords and snow zone 1.5 for approximately 6-meter spans. It is reasonable to assume that a ww truss can handle slightly larger spans, but probably not much more. I think you need to go back to the manufacturer for accurate information.
