Searching for R 2320 balance

Hi there- thanks so much for reaching out to us! 

I was able to narrow what you have down to two options. You either have our Series 380 or our Series 385 channel balance. The difference lies in the depth of the shoe. The series 385 balance has a 15-004 shoe, which is 1-3/32” deep while the Series 380 balance has a 15-005 shoe, which is 1” deep.

Please reference the below photo to see exactly how to measure the depth of your shoe to determine which series you have.

Comparison of 15-004 and 15-005

The length of just the metal on your channel balance should measure 24" given your stamping, but please confirm that this is correct before purchasing. At checkout, you will select the 2320 "option". This correlates with the spring strength of your balance. If you have any questions at all please don’t hesitate to reach out to us.
