## Questions & Answers

**Q: What is the diameter of the hole underneath the grate?**
A: Not sure of the exact diameter, but this is a snap adapter that will fit a standard 4 inch corrugated pipe.

**Q: Using 3" pipe will it adapt to 3"?**
A: yes

**Q: Does the adapter come off**
A: No, it is one piece.

**Q: I see 3 and 4 inch nominal pvc fitting this in the picture. Is that the sawn off end fitting onto the outlet, or the factory expanded end of the pipe?**
A: I do not understand  your questions.   Part# 640 will fit 3” and 4” Drain pipe and Drain fittings.  Also bell end side of the pipe, which is the equivalent of the end of a fitting.
