Question

Hi there,

Can you please help me identifying the correct Swisco products that would replace mine?

Measurements Info:
24" length without the plastic tops
1/2" width

Thanks!

Hey Matthieu. This looks like either an S351-24 or S390-24. The only difference between these two balances is the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement. See the diagram below for reference. Compare both balances with your old hardware to see what matches best. For a stamp option go with 2320.
