This is a large custom order copper rain cap for one of our Beacon Hill clients.  She wanted this rain cap to keep squirrels out of her chimney at her vacation home in NH.  More pictures to follow of this and the second rain cap installed on the rear chimney.  This cap is on the large center chimney of her home.  To see other custom copper rain caps http://www.dmstorrschimney.com/our-soot-stories/custom-copper-raincaps-boston-2
