If you're ventilating your grow room, chances are some of the equipment flanges and ducting diameters are not going to match.
These three-piece duct reducers are your solution.
You can use duct reducers to connect mis-matched diameter openings between exhaust fans, fan filters, ducting, duct mufflers, duct boosters, grow light reflector hoods and even indoor greenhouse (tent) openings.
Made of solid sheet metal, each duct reducer allows you to decrease (or enlarge) the diameter of your duct opening by 2".
Common indoor gardening sizes: 6" x 4" - Connects 6" duct opening to 4" duct opening
