Hi, I am looking for apparently proprietary fan cages for my old Addtronics 7890a server case.

The Addtronics site shows them for sale, but I think the company is out of business as it says it won't ship to me and I am in the USA.

There are two different types of fan cages in the system. They are both for 80mm fans.

Here is what they look like.

Any help would be appreciated.

Thanks.
