Ambco Window balance springs and other part

Question

Do you have these parts for an Ambco single hung window? I need two balance springs and two of the sash spring release parts (three images). The window sash dimensions are 45½" wide X 22½" tall.

Hello,

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.

As for your top sash guide, see our 18-008. Thank you and let us know if you have any other questions or concerns.
