We're based in Sausalito, California and make all the parts for the USM here, in house. If you need something that you don't see on our site, let us know, we can discuss making your custom flange or mounting solution.

Where to Find Us

We spend most of our time at the shop in Sausalito. Sometimes we're out on a boat, so call before you show up, we'll give you the full tour.
