Niuair replacement Chanel Balancer
Hello,
With this combination of attachments, you could have either an S380-30 or S385-30 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need 2950 spring strength options for your replacement balances.
Thank you and let us know if you have any other questions or concerns.
Unfortunately, we can't make out accurate dimensions from photos but if the shoe is over 1" deep, which looks like it may be based on your photos, then you would need the S385. Orders can be placed directly on our website, but you are also welcome to give our customer service team a call at (888) 991-1929 for assistance.
