  1. Looks good the delivery was on time and in great shape.

    • Charles, we are thankful for the time you took to leave us your feedback from your recent order. Delighted to hear that the RDP Rooftop Exhaust Vent Cap with Damper arrived on time and in great shape.

  2. Product is made on thin metal and fear it will not stand up considering the high price I paid and will not buy again

    • Hi Christopher! Thank you for taking the time to review your purchase. The Rooftop Exhaust Vent Cap is made from high-quality 28-gauge steel. If you have any issues with the product, please let us know and we would be happy to make this right for you!

  3. Can’t comment on the performance of the part as it hasn’t been installed. Items were as they were described, customer service answered my questions very fast, items were packaged well. Items seem to be solid compared to other brands. Really like that backdraft flap is installed on top of the actual vent duct inside of the housing and that rigid duct fits perfectly into it just like the drawing was showing.

    • Thank you for your review! We hope this item exceeded your expectations.

  4. Awesome shipping/packaging! Great product – good price!

    • Thank you for your review! Happy to hear the product arrived in a timely manner and exactly what you were needing.

  5. Boss said to light and flimsy. To big of footprint for a 6″ vent.

    • Hi John,

      We’re sorry you weren’t satisfied with this product. This item is made in the USA and constructed with heavy gauge steel. We would be happy to accept a return if the item is unused and in its original packaging.

I have a 42 inch Blaze bbq hood with 2 fans pushing 1000 cfm each. It has an 8 inch adapter. Is this the correct roof vent for this hood? Kirk asked on March 21, 2022

The 8" RDP Exhaust Vent Cap is recommended for use of up to 800 CFMs, unfortunately, it would not work for this hood.

I have a Zline remote range hood that I am looking to install in my attic. The unit contains 2- 700 CFM blowers for a total capacity of 1400 CFM. The flexible (vacuum) hose that was supplied by the manufacturer to connect the range insert to the blower housing is 8", the outlet diameter for the exhaust is also 8". The manufacturer provides no specification on the recommended ducting size, but while the diameter is small for industry standards I don't see any benefit to going with anything larger than 8" if the duct between the hood insert and blower is only 8" as well as the outlet for the exhaust. With all this being said, what size vent cap would you recommend I go with 8 or 10"? Thanks in advance! Jake asked on February 28, 2022

We always recommend a bigger vent to allow for better air flow and less stress on the cap. Our 10" RDP Rooftop Exhaust Vent can only be used up to 1000 CFM's, and our 8" model can be used up to 800 CFMs.
