cutting tip plate for main stack


not sure if this is a plumbing question and belongs over there - more to do with roughing in

I want to push a 3" stack up inside an interior wall and out thru the roof. I have a 4" hole saw to cut thru the top plate (thinking this will accomodate the 3 - 1/2 " o/s diameter of the abs pipe) with a bit of wiggle room. But this will only leave @ 3/4" of top plate on either side of the opening. I'm almost slicing right thru the top plate by the time i'm done

This is not a load bearing wall - but is this acceptable?
thanks

you should be cutting an oval hole. The top plate should be strengthened with metal straps and a metal notch plate.

thanks for the reply - I've seen metal straps all over the big box stores, but nothing like a metal notch plate - assuming this would fit around the pipe on top of the original top plate?

no something around the pipe would be called a flange. A notch plate is used so errant nails do not penetrate something that you installed through a hole in the studs. The steel strap is to restore the structural integrity of the wood you cut.
