Check pitch, gauge and drive links on the listing before you order. How this works
Same length, different chain
The number is the length; the letter is the chain. These all have 50 drive links:
| Code | Type | Pitch | Gauge | Family |
|---|---|---|---|---|
| T50 | 91VXL | 3/8" LP | .050" | VersaCut |
| R50 | 90PX | 3/8" LP | .043" | AdvanceCut |
| S50 | 91PX | 3/8" LP | .050" | AdvanceCut |
S50: same pitch and gauge as T50, different cutter. Either fits the same bar. R50: different pitch or gauge. Not a substitute for T50.
