Need to buy replacement

I'm afraid I can't use these pictures to confirm what you have. You only show the top attachment, which looks like the 19-002. The Series 385 has the 19-005. We can at least rule the Series 385 out, but I'm not sure what your bottom attachment is. You will need to carefully look over the pictures and dimensions we show on our site to confirm the best match.

Thanks! The bottom shoe looks particularly large. I would start with the Series 390 channel balance; this comes with the 19-002 top and 15-001 bottom. As long as the size of these attachments match yours I think you'll be okay.
