I have a Swisco glass door with tandem rollers. See pictures.
Can't find an exact replacement. \
Size: 11/16 wide, 4 1/4 long, steel roller bearing 1 3/8 wheels.
The door says: Um111, Series 800, SGD-LC25.
The nearest one I can find is 18-030

I live close to the ocean. While I'm replacing it is there something in stainless steel?

There are a couple possibilities. Before I check to see if we can get 81-030 in stainless steel, look at the 81-167 as another possible roller assembly. Compare the end where the adjusting screw is, as well as all the dimensions. The 81-167 doesn't have a screw frame hole like 81-030.
