One of my sash balances broke and i need to replace it. The text on the hardware says 23 5 CV CMC 7. Can you help me with the best replacement?

Thanks!

Hello! You could either have an S380 or S385 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need a strength option of 2350. If you have any further questions just let us know!
