Simpson Adjustable Length Pipe.

Has anyone had any experience with the simpson dura vent adjustable length pipe?

I guess it is adjustable from 8-1/2" to 12"

How does it adjust does it require cutting if so how the heck to you cut double wall pipe?

I am picking up one early AM tomorrow just n case it is needed for my install.

Thx.

Pelletizer,
I just did an through the wall install using a section of adjustable pipe. The adjustable pipe's "female"
end slips over the "male" end of the adjoining pipe with no twistlock. You would then attach it to the other pipe, extend it to the desired length,
screw and seal it. I would not cut it.
Pick up a piece, you can always bring it back.
Good luck.
Brian
