Hello,
I need to know which part to order to replace the one in the pictures. The metal part is 27" long and 9/16th" wide. It has the following stamped on it: 26 4 FX CMC.
Thank you!

Hey there!
With this combination of attachments, you could have either an S380-27 or S385-27 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need a 2640 spring strength option.
If you have any further questions just let us know!
