Yes, it should fit into any circular 4" piping.
If dimensions are the same it will fit OK, does not have to be corrugated.
The outside dim is about 3-7/8 inches. So, it does not work w/ the NDS 4in Corr Hub Adapter.
The circle side is 3".
It is designed to divert the water. Not sure about what you are calling a catch basin.
We didn't because we have patio blocks there, but I don't see why it couldn't be done.
Yes, screw it in place. Unfortunately the hardware is not included. The plastic is soft and flexible, easy to get through with a self tapping screw.
It can be adjusted to what ever angle you need.
Works without extending.
I doubt it, spray it.
