Channel Balance needed for a 27" x 1/2" part. Code on it shows 26 4 GU CMC 5. 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.
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.
