    Rated 5 out of 5 by from Spring loaded, Quiet. Very good. It was a replacement for a cheaply made vent that had broken. It was installed and works perfectly. The old vent was not spring loaded so the slightest breeze made the flapper go back and forth creating a noise whenever it closed. The new one is spring loaded so that it does not flap in a small breeze. It is also padded where the flapper closes sot it is very quiet. Also the new vent includes a screen to prevent bikrds or othe critters from entering. I would recommend it highly and the price is very low.

  • Can this cap be used on a sofit for a range hood?

    Asked by: Virginia
    Thank you for your question on the Broan 641 wall cap. The 641 is a wall cap only, not a soffit vent cap. Broan does not offer a soffit cap. However there are company's that do make such caps. If you have further questions please contact Technical at 800-637-1453.

    Would this be ok to use for a portable AC unit exhaust discharge?

    3/4 ton unit. This says not for use with dryer but I assume that's because of lint and not heat.
    Asked by: James
    Thank you for your question on the model 641 six inch wall cap. As long as the AC unit can handle a 6 inch round wall cap with a spring-loaded backdraft damper and bird screen, it would probably work fine. The lint problem is why it is not recommended for dryers.
