3-1/2 Inch Tractor Exhaust Silencer Weather Flap Rain Cap Muffler Cover 3.5" - Black

Well made, fit well and functions perfectly.

Is got a hole in the rear to add weight is your exhaust doesn't put out enough to blow the flap open. I used 2 square pieces if steel and a couple of 1/4oz wheel weights to get mine balanced.

Because of the layout of our house, I am forced to vent the clothes dryer vertically through the roof. For a long time I fought with the issue of getting a weather and critter free vent that did not obstruct air/lint flow. I tried all sorts of standard dryer vents and tried designing something but was not satisfied. My son (who should be an engineer like his father...) thought further outside the box than I had been and suggested this type of stack exhaust. It was a little heavy for the expected air flow as supplied, but there is a conveniently located hole. I added a bolt, nut and some washers to counterbalance the cover. The result is a dryer vent cover that meets all my needs (and is the perfect size to mate with the PVC vent pipe).

Great item fast shipping wonderful to work with great transaction as it should be

Is what it is, good quality and works great. I have it on a 3 and a half inch pipe.

Perfect if you have a hoodstack to keep elements away if you don’t have a garage.

After being installed on my chipper it fell apart after just 4 hours of running time. And I'm not just talking bolts falling out the metal housing just filed itself away.

Worked great for top on my smoker pipe.
