Hi, I have a balance that is marked 2630 BSI. It measures 27 inches long (metal channel). Both top and bottom guides have wings.The spring and cord have come apart as you can see. If you need any more info please call me. Many thanks.

Hey, David. With this combination of attachments, you could have either an S380-27 or S385-27 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 a spring strength option of 2630. If you have any further questions just let us know!
