Questions & Answers

need to put on existing pipe

Answer This Question

I don’t see why it can’t. Just use metal snips, cut a straight line, and install it where the cut is hidden towards the back of pipe where it is mostly out of sight.

    Yes, it can be cut and 'wrapped' around the pipe.

      Yes. That’s what I did. Just use metal shears.

        I am looking for a reasonable snug fit, not 1/4 - 1/2" of space around the diameter of the ducting.

          It is medium duty galvanized steel sheet. I used is to connect to hold a 7 inch duct with a 7inch to 6inch reducer for my new cabinets. It worked nicely to hold the 7"inch duct above the ceiling and provided a 6 inch connection for planned new cooking hood through kitchen cabinet. The collar will be hidden by the cabinet.
