This is 30% lighter than the standard bar. Made of two steel plates which have been hollowed out and electrically welded together. The open areas have been filled with fiber-reinforced polyamide. This bar has excellent rigidity for efficient cutting and better balance during limbing operations. Great for arborists. E Mini Light version available in 10”, 12” and 14” lengths. Ask your local dealer for assistance selecting the right guide bar for your chainsaw. Note: The actual listed guide bar length can vary from the effective cutting length depending upon which powerhead it is installed.
