Hello, If your bottom attachment has a 1" depth as shown below, you'll want to go with the S351-22 with a 2120 spring strength option. Thanks for posting! |

I am not sure if I understand your question 100%, but if you're measuring the depth of your bottom balance shoe, you want to measure it from front to back, just like in the diagram, we placed in our previous response. Does this help answer your question? |
