I live in Florida where we get hurricanes. Will the friction fit hold? What else can I do to secure it? The old top rusted away.
By Chris C. on June 30, 2016
Answer:With the potential for high winds, I would indeed utilize additional means to secure the cap to the chimney. Once the cap is snuggly in place atop the chimney system, I would utilize a 2 or 3 small "L" brackets with 1/4" screws run through the horizontal portion of the "L" bracket into the base of the cap, and another screw through the vertical portion of the "L" bracket into the chimney pipe itself.

I am replacing a metal fab chimney cap which is 9 inch from side to side. Will this fit my existing pipe which is a insulated pipe.
By Tyler M. - Fireplace Specialist on May 16, 2012
Answer:This cap will fit if your inner diameter is indeed 9". It will slide inside the pipe and attach with a tight friction fit. If 9" is your outer diameter, you will need to determine the inner diameter and get this same style cap in that size. Please note that this cap is for solid-pack chimney pipe, which is different from air-cooled chimney pipe.

I'm looking for a chimney cap that will work with my triple wall system: inner - 9", middle is 12", and outer is 15". What is the outer diameter of this cap? Will it work on these pipes and if not, what will?
By Kevin E. - Fireplace Specialist on May 24, 2013
Answer:This particular cap features a 9" pipe section to allow it to push into vent pipe with 9" inner diameter. The lid diameter is 17". As such, it would be wide enough to fully cover your customers' chimney pipe. However, triple-wall chimney pipe is air-insulated. The spaces between the two outer walls needs to remain open so that air can freely flow and keep the chimney pipes cool. This cap would prevent the flow of air within the chimney pipes. Unfortunately, we do not carry a universal fit cap for 9" air-insulated flues. We apologize for this inconvenience.

Having trouble finding cap for 30 year old wood stove chimney. The inside diameter of the triple lined pipe is 6" and the outside diameter is 9". Will this model work for my chimney? Cap broken off in strong wind storm. Biggest stove store in state can't help me.

This cap will likely not work for you. This style of cap is designed to press down inside factory built pipe with a 9" inside diameter. Of course, if there is access between the 2nd and 3rd wall of your chimney pipe, it may slide down into your chimney. For your installation, however, I would recommend our CPF-13842. This cap is designed to push down inside the 6" inner most pipe in your chimney. Please find it here:

If my flue is 9" and your chimney cap is also 9" how will they fit inside each other? Is the cap tapered to slide inside the flue?
By Chris C. on September 22, 2016
Answer:The stub coming from the bottom of the cap does indeed feature a slight taper to it, but I have had several customers utilize larger hose clamps to aid in starting the pipe stub into the chimney, and once the pipe stub is in the chimney, the hose clamp is removed.
By J W from Elkhorn WI on September 29, 2016
Answer:There is an open seam on the cap so that you can push metal together to make it smaller while fitting into the flue. It worked great.
By Alan from Titusville, Florida on January 21, 2014
I Just measured my flue for a new cap. If I'm reading this correctly this cap will fit but I would like to confirm. I removed the horrible cap I have now and the inside diameter is 9". The outside diameter measures just a little over 14". I'm including pics of my old cap. It's causing a lot of smoke and heat to be forced down onto the top of the chase and when windy outside sometimes makes the room a bit smokey. I believe a cap such as this would help this situation. Do you agree?
By Collin C. - NFI Master Hearth Professional on January 21, 2014
Answer:It does indeed appear that the current cap would be highly restrictive to flow, causing the issues you are experiencing. Given the diameters you have provided, your chimney system is likely an air cooled type, which requires that cooling air must be allowed to flow between the inner and outer walls. When your old cap was removed, did you observe open space between the inner and outer chimney walls or is the area sealed or packed with insulation? Please advise.
