The Makita® 20" Guide Bar is a solid-body, professional guide bar. This guide bar is built for tough jobs with chromoly steel for body strength and tough rails to reduce wear and chipping. A barrier in the guide bar groove acts as an oil retaining feature for improved bar and chain lubrication. Angled oil holes slope up and forward to increase oil velocity and reduce plugging by up to 80%. The replaceable sprocket nose fastens with a single rivet. It is ideal for use with Makita® Gas Chain Saws (EA5000PR, EA5001PR, EA5600FR, and EA6100PR sold separately).
