Looks like you need new balances. We can definitely help with this hardware. Your pivot shoe is an older version of our 15-180, but our newer part will still work the same way. It's also compatible with the Series 190 coil balance. You'll need the stamp off the old balance to confirm the best weight option. |

If there's no number on the old stamp, then we'll have to do a little bit of math. Please tell me the exact weight of the sash, down to the ounce. Please also tell me how many springs are used on each side. |

Oh, good! I'm glad you found it. In that case, I recommend the S190-840. This will work just as well as your old spring. |

Assuming this is the same type of system, which it appears to be, then a stamp of 5 might correspond to our S190-540. I'm just not sure why this one doesn't say "532" like the original. It should, and I don't know why it's different. You'll need to figure out if that's a 6 or 9. If it's a 6, go with our S190-640. If it's a 9, then go with (you guessed it) S190-940. |
