Hey there!

It looks like you have either our S351-22, with a 15-002 bottom attachment, or S390-22, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You will also need a 2140 spring strength option.

If you have any questions just let us know!

The stamp on your metal channel indicates the weight range your balance is calibrated to support. Your stamp reads "2140" which means you'll need to choose the 2140 option on the S390-22 or S351-22 product pages. Let me know if this makes sense or if you had any questions.
