Hello,

Could you please help me identify the correct part to order? Both the top guide and bottom shoe have wings. S377 looks to be the closest, although the top guide seems different.

Thank you,

Maile

To me, your balance actually resembles more of our Series 380. Take a look at our S380-16. This comes assembled with a 19-005 balance top and 15-005 bottom balance shoe. Confirm your measurements match up with ours. If everything looks correct, then you can go with the 1520 option that holds a sash weight of 6-10 pounds.
