GB Chainsaw Bar Adaptor Plates

GB Forestry Chainsaw Guide Bar Spacers

Precision-machined guide bar adapters for fitting selected larger-mount guide bars to chainsaws with narrower bar studs.

GB Forestry Guide Bar Spacers allow selected guide bars with a larger mounting slot to be fitted to compatible chainsaws with smaller bar studs. Each spacer is CNC machined for precise fitment between the chainsaw powerhead and guide bar.

These adapters are particularly useful where a suitable guide bar has the correct general mount configuration but the guide-bar slot is wider than the chainsaw's bar studs.

Guide Bar Spacer Compatibility

How the Adapter Sizes Work

The first number represents the chainsaw bar-stud size and the second number represents the guide-bar mounting slot size.

For example, the GBSP9-12 allows a compatible chainsaw with 9 mm bar studs to accept a guide bar with a 12 mm mounting slot.

Important Fitment Information

Check your chainsaw powerhead stud measurements and oil outlet position before ordering.

The spacer adapts the difference between the chainsaw bar studs and the guide-bar mounting slot. It does not guarantee that every guide bar with the corresponding slot width will fit a particular chainsaw.

Before purchasing or using an adapted guide bar, check:

• Bar-stud size and outside-to-outside stud width
• Guide-bar mounting slot size
• Guide-bar oil hole correctly aligns with the powerhead oil outlet
• Chain-adjuster hole correctly aligns with the chainsaw tensioner pin
• Guide bar has suitable clearance around the powerhead and sprocket cover
• Chain pitch, gauge and drive-link requirements are correct for the complete setup

Not all guide bars are suitable for adaptation. Correct mounting-slot size alone does not confirm compatibility.
