Replacement identification

A home owner from Tulare, California says:
The balance is 28 inches long not including the plastic ends just the metal part. The only identifiers on the balance are the numbers and letters in the pictures I attached which are 27 5 GV CMC 2. Please let me know if I need to send you anymore information. Thank you.

This looks like it could be our S390-28 channel balance. Look it over and see what you think! It comes with the 19-002 top and 15-001 bottom nylon fittings, so as long as they match then you should be okay.

A home owner from Tulare, California says:
This is the foot Measurement. The email said there Might be an eighth of an inch difference.
What do you think. I will take all the advice o can get.

I can't tell its exact size from this ruler, but it looks to be over an inch. If so, then I think our S390-28 is your best bet.

A home owner from Tulare, California says:
Yes sorry I didn't put it in my email it was 1 and 1/8 in. Ok thanks.
