Review on POWERTEC 70126 Inlet Flange 4 Inch by Walt Smirnoff

As usual my use of something like this is unusual. I used this flange to make a fresh air intake for my Chinese diesel heater. My heater is in a plastic container (for weather protection) and attached to the outside of my jeep. I had to dust proof all the entrances and exits so using a simple grill wouldn't work. This flange was perfect. I added a dust cap that I remove when the heating is on, and the long snout design also keeps out the rain.Super happy.
