Balancer for vinyl window

Thanks for reaching out to us! I'm afraid I'm not able to identify your balance from these photos. I'll need to see clear photos of both the top and bottom fittings in order to help. Let me know if that's something you can get for us! 

Thanks for your photos. Based on what I see here, you have either our S380-14 or S385-14, 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.

Comparison of the S380 and S385 balance shoes.

Your stamp also doesn't match any of the options available for these two balances, but that might not be a problem. You will need to weigh your sash on a scale to get the exact weight. We have a chart on both the S380-14 and S385-14 store pages that tells you exactly how much weight each one can support.

If your sash weight exceeds the options on that chart, or is otherwise not shown, let me know and we can look into alternative options for you.
