Window balance slider cord broke

Thanks for your photos. Unfortunately, replacing the cord is not possible. Once the cord snaps, you need an all new balance.

Based on what I see here, you have either our S351-26 or S390-26, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.

Lastly, I'm afraid I'm not familiar with our area, so I cannot make a recommendation for where you can buy these. That said you can order these directly on our site at your convenience.
