The rain cap with spark arrester tops off the chimney system to retain sparks and hot embers from escaping the chimney as well as to keep rain and snow, debris, and animals from getting inside the chimney.
Our chimney cap uses the same twist lock connection as the rest of our products to allow easy removal for cleaning. The spark guard mesh measures 3/4" to block hot embers from escaping but not being so small that it will clog up from creosote and ash.
Note: 3/4" mesh is not approved for use in California which requires 5/8" mesh.
