Milgard Channel Balance 22 5 BX CMC 11
Hello,
With this combination of attachments, you could have either an S380-23 or S385-23 channel balance. You’ll need to remove another balance with an undamaged bottom fitting to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need 2250 spring strength options for your replacement balances.
Thank you and let us know if you have any other questions or concerns.
Customers with Milgard windows have used the 18-188 top sash guide as a replacement. The dimensions are close to what you have listed but take a look and see exactly how we measure the part as shown on our product page. Let us know how it works for you.
