On an exterior wall or load bearing wall… if a notch
in the top plate exceeds 50% of the width then a
metal strap must be installed… OK, I got that.
But what is the maximum notch that can be cut in
a 2x4 top plate, even with the metal stap added?
I am looking for code reference and cannot find
the answer in the IRC.
Can you cut out 3" of the 2x4 as long the strap is added?
It seems that there should be a limit.
