How to measure
- Squeeze the split ends closed. The ring is cut so it can snap on; close the gap first or every number reads big.
- Measure B, the inside diameter (the hole), straight across the middle. This is the number that picks your size.
- Check A, C and D. All six sizes share A 4.1″, C .75″ and D .38″, so if those match, B tells you the part.
