    Answer: 
    The 641 and 641FA both have a mesh bird screen. The is intended for exhaust so it also has a damper. The 641FA is intended for fresh air intake so has NO damper. The answer from Broan Customer Service was not exactly correct.

    The diameter looks the same or just slightly smaller than rigid 6 inch duct, but not small enough for the duct to fit over it. Is it better to crimp the duct or the wall cap to make them mate?

    Answer: 
    Thank you for your question on the model number 641FA wall cap. The collar on the 641FA should fit into six inch rigid duct work. If you find that you need to crimp the duct work or the wall cap, we would suggest crimping the duct work.
