The crimped end of the solid duct pipe is the exact same diameter as the opening on this vent.
-
The uncrimped side of the solid duct pipe is significantly larger than the vent opening, so I feel like increasing the crimps and managing to squeeze it in would leave it under some tension.
-
Any decent range hood, if not your local building code, is going to require solid duct pipe with smooth walls.

I tried for an hour, in the attic, to compress or expand the solid duct pipe to fit inside or outside the vent opening...until the adjustable elbow I was using broke.
