Balance channel

Hello!

It looks like your balance is a match for our S351-25 or S390-25, depending on the depth of the bottom shoe. Our Series 351 has a 1" deep shoe and the Series 390 has a 1-1/8" deep shoe so you'll need to measure as shown below to see which one matches up. You will also need the 2440 spring strength option based on your 24 4 stamp.
