Can you please help identifying a replacement for my window balance (for non-tilted). The metal part is 25" long and it has U.S.B 24B. Thanks.

Hey there. It looks like you have either an S351-25 or S390-25 Channel Balance. The only difference between these two balances is the depth of the bottom nylon shoe. See below. IN either case, for a stamp option choose 2420.

Comparison of the S351 and S390 balance shoes.
