The FAMCO WDCSS wind directional chimney cap is designed to be an effective solution to chimney downdraft in windy areas. The cap separates the wind stream as it flows over the cap, while the rotating hood is kept in proper position (relative to the wind) by the wind vane. Air movement past the hood creates a partial vacuum in the flue, enhancing draft efficiency and helping to prevent downdrafts. Quality constructed from heavy-duty 26 gauge stainless steel. We recommend using Loctite c5-a copper anti-seize on the rotating bracket and cleaning creosote buildup to ensure cap functions correctly and is able to rotate without issues, this should be done annually or else as needed.
The FAMCO WDCSS wind directional chimney cap is engineered to slip around the OD (outside diameter) of a single wall pipe. For double/triple wall pipe, we also offer our WCASS wind cap adapter which will fit inside an insulated, double or triple wall pipe to create a mount for your wind directional cap (sold separately).
The FAMCO WDCSS wind directional chimney cap comes in a range of diameters from 5 inch to 14 inch with heights ranging from 14½ inch to 27 inch, see our specs sheet for more details. The FAMCO WDCSS Wind Directional Chimney Cap is manufactured by FAMCO in the United States and comes with a 1-year warranty against product defects and workmanship.

Excellent quality, works great!
This is the second cap we’ve purchased, both from Famco, as we have 2 wood stove inserts, in our home (plus another in our garage/shop). The first works great! We were having issues with smoke being blown back down, behind the insert, which would then enter our living room. This would happen in high winds, blowing across the flat, open chimney. This cap also creates a much better draft, so our fires are started way more easily. We couldn’t even start a fire if it was breezy outside (before). And the better draft helps in the summer, too. No more ‘smell’, it’s so nice!
I expect this one will work the same, for our other fireplace!

Shopped for another wind directed chimney cap since the last one worked so well. We were very happy to shop and find another cap at Famco. Delivered to our home, I’ll review and order an adapter from Famco.
Great products, great service, great Company.

Easy to install and works great! Just make sure you have good stainless steel mounting screws to secure as they are not provided.

These caps are the best thing ever. Our wood burning stoves have never functioned so well. They burn hotter and faster with almost no back drafting. If I had know that a wind cap made that much difference I would have put them on my chimneys years ago.

Although we have not yet determined it’s effectiveness in the gulf shore winds, we are pleased with the ordering and shipping process. The quality of construction exceeded our expectations. Thanks.

Arrived on time and is of very high quality build and workmanship. I am pleased with this rain cap. Won’t be firing the wood burning furnace for another 2 months but I see no reason why the cap won’t work perfectly.
