Pls tell me which balances I need to replace these. My home was built in Riverview FL in 2017 w-7500 sq ft., and 26 windows. The windows are now starting to be difficult to open and balance components are breaking (plastic tips, springs, etc.).

Hello there. This might be an S380-30 Channel Balance, with a stamp option of 2920. Just confirm the shoe depth. The shoe depth is the measurement from the 'heel' to the 'toe' of the shoe. See the diagram below. For a Series 380 balance, this measurement should be 1". Let me know if your shoe is different before proceeding.

Perfect. In that case the S380-30 should be what you need. For a stamp option, select 2920. Let me know if you have further questions.
