The duct had feedback so we put this on to ensure the airflow was one way only and not flowing back into her dryer. IT was a perfect fit with the flexible duct tubing and the dryer. I did not need to bend or crimp anything. The flapper doors work very well and it’s a quality metal product. Very easy to install. So far it seems very durable. Great value for the money! Review: Good quality. Just what I needed. - Perfect! We had a cold windy day and I felt cold air circulating out from under my range. It was pouring in from the microwave through the vent hood duct. My first winter in this home and found the vent on the outside doing nothing to prevent cold air blowing in through the microwave vent hood. This fit perfectly INSIDE the 6” duct and created a great seal to prevent any draft coming into the house through the duct. There was not room for an additional fitting as there is a 90 out of the wall into the hood. Good quality, perfect amount of spring tension, the vent van pressure opens the damper with no problem. ## Features - Home Improvement: Especially suitable for inserting into dryer duct. Perfect for use in bathrooms, garages, sheds, campers, stopping inflow of air from AC units, range hood extractors, heating systems - Easy Installation: The duct damper opens and closes automatically, allowing only one-directional airflow. The damper blades open only in the outflowing air direction when the shutter is installed. The duct valve for 8-inch duct best installed in a horizontal position and inserted fully into the duct. This also applies to vertical installation - Premium Material: The casing of the shutter is made of galvanized steel sheet. The dryer vent valve blades are made of aluminium. The shaft and spring are made of stainless steel - Great for Home Use: The inner rubber seal is used for better tightness and for noise reduction. The outer foam sealing strip provides good tightening and fixing of the backdraft damper inside the duct. The back draught valve can be inserted into a non-flexible metal or plastic duct directly, but for flexible duct you must use steel duct clamps to secure the backdraft damper - Warm Prompt: Please note the diameter of this backdraft damper is 7.9" and it can be fit in a 8" diameter pipe or hole easily.
