Duct Flange - 4 in - Steel - Powder Coated

Steel Wall Connection for Ducting - 4 in

Loose duct ends make for untidy runs and leaky joints. A duct flange gives the duct a fixed, defined connection point where it meets a wall or panel. This steel flange has a powder coated finish and comes with an additional steel ring and bolt set for joining to sheet metal ductwork.

The 4 in size suits small to mid-size ventilation runs, such as a single exhaust or intake line serving one indoor cultivation space. It is sold individually, so you can buy exactly the number of connection points your layout needs.
