Thanks for posting. It looks like your top attachment has wings, while your bottom attachment does not. That means that your balance will have to be custom made.

Before we can begin, I'll have to figure out what your bottom shoe is. Please look at the measurements for our 15-001 and 15-002 bottom shoes and note their depths. As you can see, they are 1-1/8" deep and 1" deep, respectively. Which measurement more closely resembles your own shoe?

Please also tell me the length of the metal channel. Do not include the plastic attachments in this measurement.

Finally, I'll need to know the weight of your window sash, since your stamp of 2990 does not correspond to any of our available options.
