window channel balance

A home owner from California says:
I saw "27 C" on my existing channel balance. Attached please find the top and the bottom guides of my channel balance. Please check it and let me know which model of channel balance I should choose to replace it.

Looks like our Series 350. You can verify that by checking both ends and comparing them to the ends on the Series 350. You'll need a 28" balance, S350-28, and you'll need a 2730 stamp option. I hope that answers your question.

This appears to be the same balance as the one above. If the top is the same as the 19-002, the shoe is the same as the 15-004, the metal channel is 28" from end to end, and the sash weighs 13-19 pounds, then you can use the S350-28 with a 2730 stamp.
