Vertical DWV PVC pipe support

[Dohc]

I have a short (about 12") 2" vertical PVC drain pipe that comes out of a shower floor drain and then goes into the P-trap, view from below...

View from above with shower pan and 2" PVC installed...

The shower floor drain is a wedi/Sioux Chief assembly...

I would like to firmly and securely support this short section of vertical 2" PVC pipe which will be concealed below the subfloor, to ensure no movement. What is the proper clamp or method in securing vertical DWV PVC?

"Riser clamp", and then do some support of the wings of that.

Exact spacer (we carry many scraps of various thickness), then wrap with 20 mil tape and two hole galvanized pipe strap.
Frankly, I would only expanding-foam in the horizontal portion and call it good.

Thanks for the feed back. I ended up putting blocking behind the pipe and then "clamping" with metal strapping.

Did the tub the same way...

Pipe is solid now.
