Window Balancer

Question

Hi, I have 3 Florida Extruders widows that need new window balancers.
The number stamped is 28C USB
The metal channel is 29" long
The glass is single pane, do I need to weigh it
Here are some pictures of the ends, let me know what part # I need to order.
Thanks

Hello,

With this combination of attachments, you could have either an S380-29 or S385-29 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 2830 spring strength options for your replacement balances.

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