I used these on my triple cat only briefly last year. I trimmed the end of the filter off so it fits perfectly inside the 45 degree air vent elbow piece. The elbow has a piece of rubber that goes between the elbow and the barb bell. You can get the idea of it from the pics. These are for a 2.5 inch carb bell (rear of the card where they go on). So: For sale three 45 degree elbows, 3 rubber pieces, 3 clamps and 3 uni filters barely used for $20 + shipping. PM me if interested. I accept pay pal or check.
