Replacing cast DWV with PVC

[CarolinaCrew]

I am replacing a 14 ft piece of cast iron Drain that goes between my 2nd floor, 1st floor and basement schedule 40 4 in cellular core PVC. The Drain runs along the ceiling of my basement into a wall and out to the sewer. So, how do I vertically support the new PVC between floors? I know riser clamps could be used with cast iron but what do you use to support PVC?

Riser clamps can be used for PVC as well...
We do this all the time...
