Read Answers for Duct Reducers

Will the flange for a carbon filter fit directly into one of these reducers, or do I need to clamp ducting on as well? -mike

These reducers should fit well with any ducting or filter size the reducer is slightly smaller than it's relative size. IE: 6"= 5 7/8" -Greners Staff

Will a reducer from 6 to 4 fit into a RHydrofarm Radiant hood or will i need a piece of 6 in duct to hood first then to 6 reducer? -john

All duct flanges are meant to be used with ducting. This assures a leak proof connection. -Greners Staff
