28" long window balances

Thanks for your photos. Based on what I see here, you have either our Series 380 or Series 385, 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.

I also recommend confirming the length of the metal channel. Based on your old stamp, "26 4," the length should be 27", not 28".
