Spring Balance Identification

Question

Please help me identify these 1/2" spring balance:

I believe these are S385 balances as the bottom shoe appears to be the 15-004 as it is 1-3/32" deep.

One of the 27" long channels is marked 26 5 LN CALDWELL

The other 27" long channel is marked 26 4 JN CALDWELL

The 21" long channel is marked 20 4 KN CALDWELL

Please provide your opinion on the proper models to order.

Hello there. I agree--so long as the bottom nylon shoe has a depth greater than 1", then yes, it looks like you need the S385-21, with a stamp option of 2040, and then the S385-27 with stamp options of 2650 and 2640, respectively. Let me know if you have further questions.
