Beautiful blue finish, fit right in the hole, lined up and in place. Perfect.

This is the second one I have purchased. Both had the same defect. These elbows appear to have a defect in the threads along the thru-wall section. Such that the AN924-3 nut will not thread onto the thru-wall portion of the elbow without galling. As expensive as these are - I would think they would be of better quality.
