Alenco Window -- Channel Balance Replacement

A home owner from USA says:

Hi, I need to replace the channel balances for a Alenco window. The existing balance has B.S.I 2140 stamped on it with the letter "BH" also stamped near the BSI marking. In addition, the edge of the 22" metal channel is hemmed. I was thinking that a S390-22 would work but wanted to verify that my selection was correct.

Please confirm I've selected the correct part.

Thanks for posting, Tim. Even though your top attachment has wings and your bottom does not, I agree that our S390-22 could work. I also recommend the 2140 option.
