Fiberlux Channel Balance

Question

I believe the balance is this one: https://www.swisco.com/32-inch/pd/Series-350-Channel-Balances/S350-32

But I am not sure of the weight. The stamp clearly says "31 C" as shown in the photo, but the actual length of the balance is 32". This is 32" only for the metal part, not including the plastic pieces on either side.

Hello! If your old stamp was 31C, then the 3130 option for the S350-32 is likely what you want. You can also weigh your sash to confirm; two balances for this stamp can carry 16 through 23 pounds. As long as your sash weight falls in that range then the 3130 option for the S350-32 should be perfect.
