Customer Q&A with Product Specialists
Bryant B.
from Truxton, NY asked:
My chimney dimensions on the inside are 10x15. From the description of your chimney cap w/ flue the 8x13 would accommodate my flue.
This cap/damper combo fits flues with inside dimensions ranging from 9" x 14" up to 12-1/2" x 17-1/2. So, yes, this will work on a flue with a 10" x 15" inside opening.

Lock-Top II: A Solid Cap, But Expect a Replacement Eventually
This chimney cap works well and provides good protection. I've found it typically lasts about six years before the spring fails, and you'll need a replacement. Overall, it's a decent purchase for the price.
Yes, I would recommend this item.

Stopped the summer down drafts
I have a ranch with a wood stove in the finished basement. In the summer I get stinky down drafts. This product solved that problem. Easy to install, it comes with everything needed. I would change the locking mechanism, thought. To close it you pull the cable and slide the chain into a bracket with a slot cut in it. The problem is, if you can't quite get a full link in the slot, you're forced to let open slightly to align the next link. Not a big deal but I'd change it to allow a positive closure every time.
Pros
Quality, ease of installation
Cons
Locking mechanism
