Same length, different chain
The number is the length; the letter is the chain. These all have 66 drive links:
| Code | Type | Pitch | Gauge | Family |
|---|---|---|---|---|
| E66 | 72LPX | 3/8" | .050" | PowerCut |
| D66 | 72V | 3/8" | .050" | AdvanceCut |
| H66 | 20BPX | .325" | .050" | ControlCut |
