Hey, thanks for posting. I've narrowed this down to two possible channel balance Series: either our Series 380 or our Series 385.

Now, as you can see, the only difference between these two Series is their bottom shoe. The Series 380 uses the 15-005 while the Series 385 uses the 15-004. I can't quite tell what you have based on your pictures, though. Please carefully compare their dimensions to your own hardware and see which is a better match. You will likely need to use an undamaged balance for the most accurate comparison.

My bottom shoe does not looks exactly like either one the demensions are the same as 15-005 except that where it is 1 inch it is only 15/16 inch . Please advise . Below are included photos of my shoe from all four sides.

Hey, Nancy. I'm afraid we don't have a smaller version of that shoe, but I think the Series 380 should be enough. If you find that it's too big, you can always file it down a little.
