Thanks for posting! Your balances appear to be the discontinued block and tackle, Crossbow style balance. The good news is that they can potentially be converted to  be replaced with our Series 795 Channel Balances.

To confirm that they will be a situatable replacement, you'll need to obtain a few measurements from an undamaged balance. To start, I'll need to know the length of the balance. You'll also need to double check the diameter of the balance spring/channel; this measurement should be 1/2", but let me know if it is 3/8" as this will need to be a custom assembly. 

Please also confirm the width of the bottom T-shaped attachment (it will either be 1" or 1-1/4" across the bottom of the T shape) as well as the exact weight of each window. We'll need this to select the correct stamp option.

Take a look at the video below for instructions on this balance conversion and the information you'll need to determine the correct balances.

There is a 30 day return period. Our full return policy can be viewed here.

I am confident that these should work as a suitable replacement, so long as we have all of the requested information and it is accurate. We have recommended this as a replacement solution for many of our customers over the years and our senior experts have even installed them in their own repair projects.

Once I we have confirmed the length, spring diameter, the width of the bottom shoe, the attachment on the top of the balance, and the weight of the sash, I'll be able to confirm the balances you need.

Please let me know if you have any other questions.
