trying to find suitable replacement shoes

A quick learner from Oceanside, California says:
The channel is 28 inches; the measurements of the shoe in image 1 are 1 5/8 length by depth of 11/16th counting the tabs and without the tabs depth measures 5/8". The masurements of the shoe in image 2 (which is the other end of the channel) are: 1 1/8 length by depth of 1 1/8. The outside dimensions of the channel are 9/16 x 5/8. Thank you.

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

Now, as you can see, there is only one difference between these two Series, and that is their bottom shoe. The Series 380 uses the 15-005 while the Series 385 uses the 15-004. None of your given dimensions match either of these shoes. Please carefully double check the dimensions of your own hardware and see which is a better match.
