32C balance

Question

I need a replacement balance, and can't figure out which one to order.  The metal is 33" long, stamped 32C and BSI (or B5I, 8S1, or something of that mix).  I would like the full setup with plastic ends.

Hello, thank you for posting,

It appears you have either our Series 351, with a 15-002 bottom attachment, or Series 390, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need.

You 32C stamp does not directly translate to our options, but we believe you can use a 3230 stamp that can support a 18 to 23 lb sash weight. We recommend obtaining the weight of the window sash to confirm!

Please review and let us know if you have any additional questions.
