2330 Window balance help

A quick learner from Diamond Springs, CA says:
Hi, I have a balance that is stamped 2330 the metal part measures 24 inches. It has a 350 series top and a 370 series bottom. Do you sell something like this, I didn't see it on your website. Also the metal piece measures 1/2 inch.
Thank you

Hi, Greg.

We appreciate your patience during our busy season. I can't be certain without photos but it sounds like you may need the S351-24 with the 2330 option which comes with the 19-002 top and 15-002 1" deep shoe. If your balance's configuration matches this, you should be good to go!

Hi Emily,

Thank you for the photos! I agree that this indeed looks like a match for our Series 351 if the bottom shoe measures 1" deep. However, we also have the Series 390 where the bottom shoe is 1-1/8" deep. I recommend measuring as shown below to confirm the best match.

Perfect thanks for the info, that's exactly what I needed. I didn't recognize the bottom part because it was so worn away over time.
