Hi:

I have noticed this issue since the beginning but never really investigated. What does the "Recommended Installation Clearance" on the Hanger Report correspond to for Type F springs ? This never matches the catalogue dimensions. For example, for Fig -82, Size 20 upwards movement, Anvil catalogue gives 19-3/16 while the program spits out 18.188". In this case, this corresponds to the min height x. Is that what the program always gives the user? Anvil recommends using the mid point of min and max for upwards movement + load flange thickness.

If I spec the spring to min or max dim x for install height, won't this affect the loads and subsequently the cals?

Please advise.
