I have a gate that is framed with 4x4's. I want to put a doorknob in
it but am having trouble finding doorknobs that fit doors over 2"

thick doors?

Did you ever think about routing out a recessed area
on either side of the 4x4? You could remove 3/4" to 1" of
material from each side making a large enough indentation
with enough room for your hand to grab the knob.
Just a thought......
