I bought 3"sewer pipe and stuck it into the tubing of the blower 10'. I added 2 90's on the end for directing the air into the gutter. By the way this is so I don't have to get on top of 75 buildings. Then I got real smart and added another 10' so I could do 2 stories. It takes a little to get use to because the air flow is what gets the whole thing in the air. So you have to find the right speed so it stays in the air but doesn't blow back over your head. I need to post a picture of it. It does work.
