The Makita® 20" Guide Bar (E-00153) 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 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. It is ideal for use with Makita® Gas Chain Saws (EA5000PR, DCS6421RFG, EA7300PR, EA7301PR, EA7900PR, and EA7901PR sold separately).
