So I ordered this chimney cap in 6" round - Chim Cap Forever Round and they sent me one that I don't even see on their website, or anywhere else. What they sent is a cross between this Chimney Cap and the one above. Basically it looked like what I ordered, with a lower screen height, larger round top (that overhangs the insert portion of cap, and lip around center hole to prevent water from dripping down liner.
The one they sent obviously will provide better weather protection, but the original one I ordered had an 8" screen height as opposed to 5". Would that 3" make that much of a difference in draft? I know it will be better than what I had, as the installer left maybe (if I'm being generous) a whopping 1" between end of liner and my old multi-flu cap.
