Hello,
Thanks for writing in! Your channel balance assembly appears to be a plain channel, tilt window balance with a 15-044 Balance Attachment connected to the bottom of the balance. This will need to be a custom made assembly.
I am happy to get an order link made up for your, however to confirm pricing and availability there are a few details I'll need to confirm. To start, is the length you confirmed the balance including the attachments or just the length of the channel. If it includes the attachments, I'll need to know the length of just the metal channel.
I'll also need to see a photo of the top of the balance and how it installs at the top of the window. This will be important to ensure the custom balances are assembled correctly.
Please also confirm the exact weight of your sash. Unfortunately, I will not be able to cross-reference the stamp from your balances with the stamp on the replacements.
The shoe compatible with the 15-044 is the 15-216 T-Lock Pivot Shoe. To confirm that this is the right replacement carefully review and compare the dimensions below.
We do not carry an exact match for your existing pivot bar but our 26-402 should work well as a replacement. You may need to drill a new installation hole to install the new bars.
Take a look over the dimensions to see if this is something that could work for you.
