Hi, I'm trying to identify this part. I can try to add any additional info that is needed to help identify. The plastic pulley broke on the one balance and I need to get two replacements so I can change them both. Thanks!

Hello, thank you for posting,
It appears your window uses either the Series 351, with a 15-002 bottom attachment, or Series 390, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need.
Please also confirm the length of the metal channel excluding the nylon attachments and provide the number stamped on the metal channel. Thank you!

Comparison of the S351 and S390 balance shoes.

The metal channel is 29 inches excluding the nylon attachments. The number is "28 3 Caldwell HM"
