Single flue caps attach to the flue. For chimneys with a single square or rectangular flue, select a chimney cap from those shown below. You will see
chimney caps that attach to the flue with a clamp like the clamp on an automobile's radiator hose. Others attach to the flue with set screws that press against the flue.
Which Metal is Best for a Chimney Cap?
Single Flue chimney caps are manufactured from stainless steel, copper, and galvanized steel. Stainless steel is the best value for the dollar. Copper is the most elegant, especially for
historic or upscale homes. Stainless steel and copper chimney caps come with a lifetime warranty. Some stainless steel caps can be powder coated with black or colored with heat
resistant finishes. Galvanized steel is the least expensive and the least durable. Galvanized steel chimney caps are painted black.
Copper is not recommended for light colored chimneys. Stainless steel is the preferred metal for salt water climates.

Still have questions about just what type of flue you have or which chimney cap you should select? Just call our
friendly Chimney Cap Experts at 888-834-7375 or e-mail us your question or concerns.
If your single flue does not stick up at least one inch, you can use either a top mountchimney cap (also known as a multi-flue chimney cap) or a single flue chimney cap with a set of
"legs." The legs fit down inside the chimney flue and securely hold your chimney cap in most situations. We do not recommend the use of chimney caps with legs especially in areas
with high winds. A top mount chimney cap is always a more secure choice if your single flue does not stick up at least an inch.
