I need new channel balances please

Thanks for posting. This looks like either an S385-21 or S380-21 Channel Balance. The only difference between these two balances is the depth of the bottom nylon shoe, as shown below. Measure your old balance's shoe depth to see what matches best. For a stamp option choose 2040.

Comparison of the S378, S380 and S385 balance shoes.

Great. These balances can be ordered directly through the online store. From the S380-21 shop page, simply click "Add to Cart", then click "checkout" in the top right corner of the screen. Don't forget to select the stamp option of 2040, as well as the quantity you need. Let us know if you have further questions!
