Are these in stock at the store?

No, Home Depot does not carry the BigTops in stores.

I need one that is 16x16

Asked by Aaron August 21, 2020

Answer

If you are looking for a chimney cap to bolt onto your masonry flue tile, take a look at model # CBO1515. It fits outside tile dimensions: 13.75 in. x 13.75 in. to 16 in. x 16 in. If you are looking for a top mount chimney cap that sits on the cement, you will want to measure from brick to brick to ensure this model # BBT1717 has enough room to mount properly with the flanges. BBT1717 has 8" mesh so your tallest flue tile should be 3" or less.

Answer

Sounds like your chimney is a shroud that houses the flue of a prefab hearth appliance. It is vital to learn about your appliance and venting. You can locate the Manufacturer & model number from the unit and learn the guidelines/requirements/limitations of the system. This HY-C chimney cap on this web page is intended for masonry chimney applications only. Call us (800-325-7076) for further assistance.

So this won't work if my chimney is 17.5 x 17.5?

Asked by Michele December 5, 2018

Answer

The BBT1717 measures 17" x 17" from screen to screen. It is designed to mount on a flat chimney top with flanges measuring about 1 1/4" on each side. BBT1717 requires a 20" x 20" masonry chimney top for the 24-gauge galvanized steel base flanges to mount properly.

will this work on a 16.5 x 16.5 brick chimney?

Asked by topper February 17, 2018

Answer

Thank you for your inquiry. If the 16.5” x 16.5” is your outside brick measurement, no the 17” x 17” cap will not work. If it is the outside brick measurement you need the BBT1414. If your chimney has a clay flue tile exposed out of the top the screen wire mesh should be 5” taller than that height. So if you had a glue sticking up 5” you would need the BBT1414K-10W which has 10” high mesh.

Nice very well made one solid piece, but the measurements are inside measurements. Outside is 20x20 I had to return it and get the 14x14 which was a piece of crap. Very flimsy had to be put together. Not the same quality as the larger one.

Basically, fit for purpose and relatively easy to install. Comes fully assembled with 4 hex head concrete screws, a tube of construction adhesive and simplified installation instructions. In high wind environments, you might want to consider additional screws. Not specified, but it requires a 5/16" ratchet wrench to install easily.

Chimney cap was used at the top of an outdoor fireplace. Good quality and application for that purpose. I'm not a professional, though. It was slightly off balance when put on the top, so when the glue that was provided was put down along the chimney edges, all the metal surfaces of the cap weren't touching it. We ended up deciding to skip that step and just bolted it down on all sides. Only 4 bolts were provided, so we purchased 4 more to use to secure it more.
