Description
This is a collar to mount flexible, 5" accordion duct to a drop ceiling or plywood, etc. It screws in to the duct.
The outside diameter is 169mm to allow it to be printable on most printers.
I have added a second model that includes screw hole studs for mounting the collar to plywood or like material.
