Hi,
From the pictures I attached can you tell me the channel balance I need and the option.

Thanks,
Sue

Measure like I'm showing in the photo below. If you get 1", based on your winged attachments, I can tell you need Series 380. If it comes out as 1-3/32", then you need Series 385. The option should be "3230" on a 33" balance, but you can check that by weighing your window sash and measuring the length of the metal channel.

Thank you. Seems like a fine line between 1" and 1 3/32" but I think I've decided on the 1". I'm more confident about the 15/16" measurement, so I will order the 380 Series, 3230, 33". It's on back order now but hopefully will be available soon.
