Q:How is this installed? Obviously the side with the tabs go into the opening you cut in the trunk so you have the smooth part sticking out. How do you screw a vent cover onto this since there is no flange?

      Q:Can I use this for my stove vent
      by|Apr 4, 2023

      Answer This Question

      A:  Galvanized metal is toxic when heated over about 400*F. If your stove might heat the exhaust going thru galvanized metal to over 400*, you need black vent pipe, not galvanized.

      by|Nov 15, 2023

        A:  Yes, if the stove vent manufacturer allows. If you have any other inquiries about our Master Flow products please contact Technical Services at warrantyllbp@gaf.com.

              Well built and I did not have to unfold it
              Built well enough for the job. Some previous reviews mention that the collar came flat packed and they had to unfold and reshape it. Mine came fully assembled and ready to use. I used it to repair a vent on a stack and add a new one to the same stack. I trimmed the back to fit in the 3.5" deep stack.

              This is supposed to fit inside the outside vent…it does not without buying a crimping tool to crimp it down to size.

              Used this to make an extension of the flue on top of arange hood so that it would reach the duct in the cabinet above. worked pretty well. It's a bit pricey for what it is, but it saved me the time of fashioning one myself.
