It is very good quality and well-made. Someone needs to come up with a fitting to fasten the copper roof vent, to the aluminum vent duct. Because of dissimilar metals that will create electrolysis and corrode I made my own coupling to prevent that from happing. The 4” vent rubber coupling has a larger inside diameter than the outside diameter of the 4” aluminum duct. I flattened a piece of 3/4” refrigerant tubing insulation in both ends of the coupling and works great. The second picture is the same for a 6” copper roof vent.

Well made, solid product. Much more sturdy than what you’d find in the big box stores. Feels like it will hold up well.

Second roof vent I’ve purchased from RD. Their quality matches that of other companies for a lower price point.
Michael, we are delighted to hear that you returned for another order with us! Thank you for the review on our Copper Rooftop Exhaust Vent Cap with Damper and Bottom Extension. We look forward to any future purchases from you!
Fast service of a quality product.
Thank you for reviewing your purchase. We appreciate your business!
Hi. I liked the products. We used your company for the first time. Five days for delivery, which was good. The only thing would be that you use aluminum dampers inside and I’m Not sure Why you don’t use copper.? Since it could cause galvanic corrosion. And I live and work by the ocean. Plus the gasket didn’t go All the way around the rim of the inside hole. Otherwise All is good. I would use you again. Ty Mike M.
