The wrap around hanger is used in free hanging gutter applications where there isn't a fascia board to attach the gutter hangers. The hanger is a combination of two parts that are riveted together. The one part wraps entirely around the gutter. The two parts are riveted together with the second part being nailed or screwed to the roof deck.
