Hello, thank you for posting,

With this combination of attachments, you could have either an S380 or S385 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment.

The length of the metal channel excluding the nylon attachments should measure 35" long and you will need a 3450 stamp option. Please review and let me know if you have any additional questions.

Comparison of the S378, S380 and S385 balance shoes.

My bottom attachment measures 1-3/32" ... so I have the S385.

Metal channel measures 35"

What exactly is the 3450 Stamp Option... Needed for both?? This will show up when I order the S385??

Thanks so much for this help

Hello,

Yes, please review the S385-35 with a 3450 stamp option. The stamp option is the strength of the spring needed to support the window.

You will need to choose this option on the product page to add to your cart. Let me know if you have any additional questions!
