Channel balance

A quick learner from Jax, Fl says:
I need to replace to 30 inch by 9/16 channel balances. Can you help me identify the part I need to order using this information? Thanks

Hi there!

We sure can. Your balance resembles either our S380-30 or S385-30, depending on the depth of your bottom shoe. The Series 380 has a 1" deep shoe and the Series 385 has a 1-3/32" shoe. You'll need to measure as shown below to see which one matches up. You will also need the 2930 spring strength option, based on your 29 3 stamp.
