I have a channel that is 16" long, metal to metal and 1/2" wide. It has 151 KN Caldwell imprinted on it. Do you have a match
Bottom Shoe: Looks like 11/16”
The depth of the channel where the nylon fitting sits is 9/16” if that helps

Hello,
With this combination of attachments, you could have either the S380-16 or S385-16 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 1510 spring strength options for your replacement balances. Thank you and let us know if you have any other questions or concerns.
