## Questions & Answers

**Q: Is this exactly as pictured or are there holes on the outside-facing plate opposite the tabs? Looking for a solid rim.**

A: Part # 1243 fits the following pipe:

3 and 4 inch Corrugated, Sewer, PVC Drain , Triple wall and sch. 40 pipe.

**Q: I have an existing 12” collection box (w/out outlets.) I need one side to connect to a 4” pipe, but I need the other side to be solid. Will this work?**
A: I purchased it to fit between a 9" grate (#991) and a 4" pipe.   It fits perfectly onto the pipe and into the grate, so I assume it can also be used to connect to a 12" collection box.

**Q: Will this fit a nds flow-well fwas24wh ?**
A: Don’t know but it did not work on what we purchased. The cut outs were not marked on the tanks we has.
