Channel Balance Replacement

 It looks like you have either the S380-30 with a 1" shoe or the S385-30 with a 1-3/32" shoe. To determine which series is needed for your window, look over the dimensions from the diagram below to confirm the depth of your bottom shoe. Let me know if it does not match either measurement. 

Comparison of the S378, S380 and S385 balance shoes.

It is a bit difficult to read the stamp on your balance, can you please confirm what that stamp is?

Okay, great. So you'll need the S380-30 with a 2910 stamp. You may use the website to place your order.
