Customer Reviews
“Rossi - high quality at a reasonable price. Also great friendly service.”
Jimmy Wright, Owner
Wright Comfort Solutions | Hollis, OK
“I think it is safe to say that I am probably one of the oldest customers of Rossi and not one time have I ever had an issue with their Customer service or the quality of their product. The first time I saw their Rossi Dampers I knew we needed to start using them in our shop and we have saved many hours of fabrication time because they are so easy to install. Rossi is and has been over the years the best company I have ever had to deal with and I have been in the sheet metal trade for over 45 years.”
John Welch, Sheet Metal Shop Superintendent

"Really impressive product. I wish we would have had it for years as it would have solved several balancing issues.”
Byron Hughes, Sheet Metal Sales Rep
R.B. Akins Company | Oklahoma City, OK
"I am very well pleased with your dampers. Wish I had known about these 30 years ago… I first used the wingnut types since that was all my suppliers offered. Never was too happy with them and you never really knew just what position you had them in because there is so much play in them… It is only recently that I discovered Rossi and use these dampers exclusively now. Thanks for a great product.”
Michael Johnson, Owner
Atlantis Heating & Cooling | Decatur, GA

"Top notch products and service!”
Bobby Smith, Production Manager
Dixie Metal Products | Memphis, TN
“Thank You for making such a great product! I firmly believe that using your dampers exclusively has set us apart from other sheet metal contractors in our area. When air balancing contractors find out we performed the work on a project ahead of them, they know they won't be wasting time looking for damper handles buried under insulation, or struggling to adjust an inferior quality regulator.”
Tim Angelosanto, Vice President
Eastern Vent Systems, Inc. | Pelham, NH
