channel balance help

Hi there. Take a look at both our S351-25 and S390-25 channel balances. The only difference between these two balances is the depth measurement of the bottom balance shoe. The depth measurement of the bottom shoe for the Series 351 is 1" and for the Series 390 is 1-1/8". Measure your bottom shoe, like in the diagram below, to determine which of the two would make a better match. Whichever one chosen will go with the 2420 option.
