Do you guys have a preferred way to make up a flexable duct connection with that material that comes in a continous strip made from rubber and metal?
Looking at the connection where the two ends come together.

Huh, never seen that. Why not just use a piece of round duct? Usually, only use "socks" on Hard duct. Why the? would you want to add needing a extra expensive machine to do this?
Required per print
What is "socks"?
Pretty much the way durodyno showed it. Fold up the excess canvas and staple it. seal up any holes from the inside with some duct sealer, you don't have to crazy with it, the holes should be small
We use flex connectors on every package unit install, just as the instruction shows. I install the joint in the center on the bottom with mastic inside, to prevent leaks. Add a piece of ground copper from side to side of flex connector, twisted around a screw. We also use junior flex~4", and extra flex~9".
There are two ways to do things, Right and Again.
Whenever we've ordered them from the sheet metal shop, they spot weld the metal together then staple the canvas or rubber like stuff. They are some sort of heavy duty industrial staples, not staples from the stapler on your desk.
I spot welded and used silicone on the flap and tiny holes in the corners. I went longer than they show like 5" on the flap part. Bent a angle to stiffen it up like they showed too. I'm happy with the way it turned out. Thanks for the ground tip.
I remember guys sewing the canvas. But at the same time we were using pan head sheet metal screws instead of zip ins.
I used to turn the canvas to metal seams up 90 degrees. Makes for an easier connection and looks more defined.
