Channel Balance Replacement

A home owner from new Jersey says:

I need to replace a number of balances, the numbers stamped on the channels are: 2810 BSI, 2830 BSI, and 2440 BSI with a backward C. Having trouble identifying the balance shoes. The top shoe I am confident is a 19-002, however, the bottom shoe could be either a 15-001 (series 390) or 15-005 (series 351). They appear to be the same shoe. Can they be interchangeable?

Hey, Doug, thanks for posting. Our Series 351 actually uses our 15-002, not our 15-005. Is that what you meant?

If so, the difference lies in their depth. You will need to measure your own shoes and see which is closer to your own.
