Numbers on channel balance

Hi there!

This looks like it could be either our S351-35 or S390-35 channel balance, depending on the depth of the bottom shoe. The Series 351 comes attached with a 1" deep shoe and the Series 390 comes with a 1-1/8" shoe. Take a look at the image below to see which one matches up best. You'll also need to select the 3450 spring strength option.
