Solved an rv furnace airflow balance issue.
When I bought my rv, I noticed that the furnace was totally out of balance and dumped all of the air into the living area and hardly any air was going to the rest of the trailer. I tried blocking the vent with plastic and tape, but neither worked. I placed this damper in the line going to the living area and suddenly had infinite control of the flow to the area. I only had to make a slight adjustment, but the result was perfect. The other part of the trailer now has better flow, and the heat distribution issue with the furnace is resolved. The valve is easy to adjust and the lock screw insures the valve will stay where you set it.
