GB ProTop Titanium Narrow Kerf Bar SN .325" .050"

GB ProTop “Titanium” Narrow-Kerf Bar — Stihl SN / D025 (12 mm), .325" × .050"

Built for tree care and pro users who want fast, efficient cuts with lower load. ProTop Narrow-Kerf uses a solid, heat-treated alloy-steel body and a replaceable sprocket-nose tip. The reduced kerf width delivers quicker cuts with less power draw and precise control on medium-size saws.

Key Benefits

• Faster cuts, less load: Narrow-kerf rails remove less material per pass.
• Durable rails: Heat-treated solid body resists groove and tip wear.
• Balanced handling: Precise control for pruning, limbing and felling.
• Lower lifetime cost: Replace the nose assembly instead of the whole bar.

Fitment Checklist (Reduce Returns)

• Confirm your bar mount is SN / D025 (Stihl 3003, 12 mm).
• Confirm your rim/drive sprocket is .325".
• Use only .325" × .050" Narrow-Kerf chain. Standard .325" × .063" or any 3/8" chain will not fit.

Important: Requires .325" drive sprocket. Do not use with 3/8" sprockets or 3/8" chain—mismatch can cause damage and void warranty.
