 supporting vertical DWV pipe
Author: roundrightfarm (WV)

I'm installing a 30' vertical 1 1/2" vent that passes right in the middle between two studs. What is the best way to support this so that the elbow at the bottom does not have to provide all the support. It is too far to strap it to a stud. Is there a good way to support it where it passes through the wall's sole plate or top plate? Should I run a 2x4 block between the studs to strap it to? Or is there a better way? Thanks

you want a riser clamp...
simply clamp it around the pipe so it is resting on the 2 x 4..

A riser clamp will look like this, but you'll need a smaller one:

WHY? Just wrap some tape around the pipe where the clamp goes and it will fit perfectly.

So the riser clamp will sit on top of the sole plate 2x4 or top plate 2x4 and the part that sticks out on each side of the clamp simply holds the pipe up by resting there?
