Window balance

Hello there!

Thank you for reaching out to us. With winged top and bottom fittings like this, the Series 380 and Series 385 came to mind. The Series 380 has a 1" deep bottom fitting and the Series 385 has a 1-3/32" deep bottom fitting. 

Comparison of the S378, S380 and S385 balance shoes.

We don't have a balance with a 15/16" deep bottom fitting though. I wonder if yours has just worn down over time from use and was once 1". 

As for the length, the metal channel should measure 30". We can only supply balances that measure on the full inch, unfortunately. 

Yes, that's correct! You'd want to go with the 2950 option since your balance has a 29-5 stamp.

I'm afraid we can't guarantee the 30" length will be a direct fit for your old channel length but our return policy can be found here just in case.
