The Makita 18" Guide Bar is a commercial guide bar. It has a laminated body and is designed for use with low profile chains for increased cutting efficiency. The slim contour provides less weight and increased maneuverability. This guide bar is built for tough jobs with chromo 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. It is ideal for use with Makita Gas Chain Saws (EA5000PR, EA5001PR, EA5600FR, and EA6100PR sold separately).
