Hello there! It appears you have either our S380-26 or S385-26 channel balance but the best match will depend on the size of the bottom shoe. Our Series 380 has a 1" deep shoe, and the Series 385 has a 1-3/32" deep shoe. Refer to the image below to see which one matches up. You will also need the 2550 spring strength option. Comparison of the S380 and S385 balance shoes.
