The Dryer Duct Lint Trap will help save you money as well as reduce the risk of dryer fire by keeping your dryer duct clean and free of lint. This product acts as a secondary lint trap for your electric clothes dryer. It installs easily onto your dryer transition duct and collects additional lint that is not captured by the Standard dryer lint trap. This helps to eliminate unwanted and excess lint within the duct and reduces the risk of a dryer fire occurring. It also allows the air to pass through.
