This is for the sink drain vent (2”). Want to make sure we get the underground plumbing correct (which we are doing now) before I order the cabinets. I need to get the vent from the sink drain to the existing vertical vent.

I realized I included the wrong product code on my original post.

For a 18” wide 34.5” tall B0DPULLOUTTRASHM, can you confirm my understanding of the cabinet construction?

side panels are 3/4” each
back panel is 3/4”? How tall is the top panel in back of the cabinet I see in the cabinet (attached)? What is the elevation of it?

So, for a cabinet depth of 24”, I will have:
24” – 3/4” (rear piece) = 23.25” clear depth inside cabinet (without trash cans inside)

Height of 34.5”, I will have:
34.5” – 4” (toe kick) – 3/4’ (top) = 29.75” clear height inside cabinet

Width of 18”, I will have:
16.5” clear width inside cabinet (without trash cans inside)
