Please identify matching Channel Balance

Question

Marking on metal channel: 2430. Metal channel is 25 in long. Both ends are winged. Window is old WindowMaster. It does not tilt. Channel width is 1/2 in. I am guessing Series 385. Looks like bottom guide is 1 3/32 in. My top fitting is black in color.

Hello,

With this combination of attachments, you could have either the S380 or S385 channel balance. You’ll need to measure as shown below. If you're sure the shoe measures 1-3/32" deep, the S385-25 would be the way to go. The color of the end fittings does not matter in this case.

You'll also need 2430 spring strength options for your replacement balances. Thank you, and let us know if you have any other questions or concerns.
