I have an outdoor fireplace with extended flue 18*22" od. Can I get a dampener to go inside this cap to keep out rain?

Our Answer:

Unfortunately, this cap is a bit larger than any of the damper caps we currently offer. Please see this cap for something you may be able to make work for your application: Lock-Top 17 in. x 17 in. Energy-Saving Chimney Damper The base of this cap is a 18 1/4" square, so you'd have a little room on your long side to cover. If you are able, you can use some strips of metal (preferably stainless steel) from a sheet metal shop and seal the opening and install this cap, which obviously works as both cap and damper.
