Replacement channel balances

Question

Hi - see attached photos.

Appears to be a Caldwell with marking 24 4 JK CALDWELL

It is 1/2" width (per your instructions)
Metal portion length is 24 and 7/8ths inches
Neither plastic end has a wing (you'll probably notice one is cracked)

Can you recommend the right replacement?

Thanks!

Hello,

It looks like you have either our S351-25, with a 15-002 bottom attachment, or S390-25, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need a 2440 spring strength option for your replacement balances. Thank you!
