Husqvarna chain sizes
Husqvarna publishes bar and chain combination tables in its operator manuals, listing bar length, pitch, gauge, chain type and drive-link count per model. Its chain codes — H30 and X-CUT SP33G for .325″, H80 and H81 for 3/8″, H37 and H38 for 3/8″ low profile — are the cross-reference keys on every Husqvarna page here.
