ABSTRACT:
A collapsible chimney cap which is stored in separate components and assembled at the point of installation. The connections between the separate pieces when assembled form smooth corners without external metal protrusions which could injure an installer or other person near the chimney cap. The chimney cap's connection mechanism also strengthens the assembled chimney cap by providing multiple points of connection. Each side piece has a insertion portion with internal protrusions which fits inside a receiving portion of an adjacent side piece. A roof is then attached the side pieces to complete the chimney cap.
