    • Wall cap is made of 24 gauge CRCQ steel construction with a black electrically-bonded epoxy finish for durability and long life
    • Sold as 1 to a carton
  • Rated 4.3 out of 5 by 6 reviewers.
    Rated 4 out of 5 by Well made but duct too short Nice to find made in the USA quality. Duct is too short for 2x6 walls so plan on buying an extension piece of ducting if you have the bigger studs. May 8, 2015
    Rated 4 out of 5 by Broan wall vent Product looked to be put together well for sheet metal. It was delivered on time and I am very pleased with the service I received. July 4, 2012
    Rated 5 out of 5 by Quality Item Exceptional quality item, heavy duty steel. Black gloss finish, really looks good. Would purchase again and recommend to anyone who is in the market for a new vent. April 23, 2011
    Rated 3 out of 5 by Wrong Picture This Broan wall vent is a 3.5x10 rectangular wall vent, painted black. That is the product I needed and I cross referenced the part number with Broan literature to be sure I bought the right thing. The website has the wrong picture, but the right part description. The product is good. The damper leaks a bit, but I did not expect better at this price. January 13, 2011
    Rated 5 out of 5 by Broan 639 Duct Wall Cap Excellent product at a great price. Fits perfectly with the other Broan duct accessories that Venting Direct sells. September 30, 2010
    Rated 5 out of 5 by Duct Wall Cap is Great Exactly as advertised. Fast delivery. Easy to use website. Would recommend both product and website! August 30, 2010

    Answer: 
    Thank you for your question on the model 639 wall cap. The 639 has a spring operated damper and normally would not rattle in the wind. Please contact the Technical Service Department at 800-637-1453 for assistance.

    I supposed I could spray paint it but that's another step. I can't believe anyone would want black.

    Answer: 
    Thank you for your question on the model 639 wall cap. The decision to make the 639 in black is a marketing decision. We do have a model 649 that has the same features as the 639 but has a natural aluminum finish.

    Installation instructions show the cap mounted horizontally.
    Can I install the cap pointing down 45 degrees from horizontal?
