Hello there. I am not certain this is an Extended-Travel balance. It looks like it may be a standard issue one to my eye. Can you show me the top nylon attachment, not just the bottom one? We need to see both for identification. Can you also confirm the metal channel length, not including the end attachments? Many thanks.

It looks like the length is 22inches ..the stamp on the balance reads 2170
i have 2 windows and it looks like 2 balances are needed for each..

Thanks for confirming the length and stamp. You still have not shown us the top nylon attachment. We need to see it, as well as the bottom one you have shown us, for full identification. We should be able to narrow it down from there.

Thanks, that's it. This is either the S351-22 or S390-22 Channel Balance, depending on the bottom shoe depth. See below. For a stamp option choose 2170.
