I would like to order channel balance:

From all of the measurement it looks like I need - 27" Series 351 Channel Balance
Product Code: S351-27

Marking
26 4 Caldwell KM


Measurement
1/2 wide by 27 length

Can you confirm this before I order the part.

Thanks,

John

Hey, John. I can't confirm whether the Series 351 is what you have or not without knowing more about that bottom shoe. It could either be the 15-001 or 15-002, but I can't be sure based on these images. Check out the diagram below and tell me which is closer.

If it's 1", I would stick with our Series 351 balance.
