What's the question??
This hanger is for rough dimension lumber. Your joists will be nominal dimensions. Sistered 2x10s will be 3 inches wide in reality, so this hanger is too wide. I easily modified it with a hammer and a vise, but your better off to not order one dimensioned for rough lumber.
Yes they are true 4" X 6" and accommodate rough lumber of those dimensions. I had a couple of pieces of lumber however that were larger than 4" wide and I had the trim them back to fit. No big deal.
these will fit actual 2" thick lumber. not for 1.5" joist.
