These balances are in a house that was built in 1984. Measures 25 in Long. And it says 24 30 < on the back.

Hi there! Thanks so much for posting. Based on your photos, it looks like you have either our Series 351 or our Series 390 balances. The differences between these lies in the shoes on the end of each balance. Compare the 15-001 & 15-002 and see which one matches yours best. The Series 351 channel balance has the 15-002 shoe while the Series 390 channel balance has the 15-001 shoe. The 15-001 shoe is 1/8" larger from front to back. I hope you find this helpful. Please let us know if you have other questions. |
