Weight spec

Question

I’m trying to find the weight category for my window part. I know I need SWISCO Series 390 Side-load Channel Balance Sash Support System part snd I see the numbers "31 3 JQ Caldwell" imprinted on the side of the piece. Does this mean weight # 3130?

Hey there. Yes, if you're certain you have the S390-32 Channel Balance, the 31-3 stamp means you should select 3130 as the stamp option. Let us know if you have further questions.
