References identify matching pitch, gauge and loop length. Cutter design, safety characteristics and manufacturer-specific features may differ.
Confirm Fitment Before Ordering
Check all three specifications on the guide bar or existing chain:
Pitch: .325 inch.
Gauge: .050 inch / 1.3 mm.
Drive links: 81.
Count the drive links that run inside the guide bar groove, not the cutting teeth. A 20 inch bar may require a different drive link count depending on its design.
This chain is not interchangeable with 3/8 standard or 3/8 low profile chain, .058 or .063 gauge chain, or loops with a different drive link count.
Additional applications are possible on equipment using this exact configuration.
Care and Maintenance
Maintain proper chain tension, adequate bar and chain lubrication, and sharp cutters. Follow the chain manufacturer’s sharpening instructions for file diameter, filing angles and depth gauge settings.
