Balances

Hello there. It looks you have either Series 380 or Series 385 Channel Balances. The only difference between these two balance Series is the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement. See the diagram below for reference. Compare both with your old hardware to see what matches best.

You then have to choose the proper lengths for these balances. The balances stamped 26-4 should have a metal channel length of 27" (the end fittings are not included in this measurement), whereas the balances stamped 23-3 should have 24" long channels. In short, this means you need either the S380-27 or S385-27, as well as either the S380-24 or S385-24. Finally, you'll need to choose a stamp option. This designates the strength calibration of the balance. Regardless of what Series you have, for the 27" balances you'll choose the 2640 stamp option, and 2330 for the 24" long balances. Let me know if you have further questions.
