Window Spring

Question

Hi There.

Can you help me with the correct window spring for my front window? There are so many options and I want to get it correct. The window is single hung and does not tilt. The metal piece is 31" in length and 1/2 wide. Please let me know if you need any other pictures. Also, would I need to buy new plastic clips as well? Please call if you have any questions.

Thank You.

Justin

With this combination of attachments, you could have either an S380-32 or S385-32 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. You'll also need 3140 spring strength options for your replacement balances.

Thank you and let us know if you have any other questions or concerns.
