Small square-flange eyeball vent. Made from aircraft-grade 6061-T6 aluminum and hard anodized, it weighs just 3 oz. Mounting flange is 2.20" square, with a hole mounting pattern of 1.70". Vent adjustment is 25 degrees of freedom from the vent centerline, and has an opening of 1.2" which is much larger than vents typical of this size. |

We recommend using 2" ducting with these eyeball vents. Standard breeze clamps will work fine to clamp the connection.
If the holes are on a 1.7 center to center pattern then if you were to measure hole to hole on an angle (top left to lower right for example) its almost 2.5 inches.
