Looking for a recommendation for a company that might have damper for a 4 sided fireplace. We found one that will build a custom damper but would prefer to find one already manufactured.

Thanks

I don't know of one, but I can tell you how to build one. It won't draw perfectly, but it will draw better than a normal damper.

Read this first:

Then here for the plan:

If you want a damper with this, you will have to use a top of flue damper. Note that choking down the opening sizes, especially on the long sides, will help.

I would push for a 2 sided though, they still don't draw well, but you at least have a chance. Built to this plan they sometimes work without doors, other types I have seen do not:
