## Questions & Answers

**Q: I have a squashed circular manhole min dimension 470 and maximum 490mm. Will this fit over?**
A: Not sure if you saw the hole requirement is 450mm - if the hole is bigger than that it won't fit - I measured the hole size and money was 450mm and it fitted perfectly.
I hope this helps?
