Oregon Power Match Bars are the industry standard for professional users cutting clean wood. Super-tough chrome-moly steel provides superior bar-body strength and tough rails with excellent resistance to wear and chipping. The Power Match bars nose fastens with a single rivet and are securely held by wide, strong, overlapping ears. The long nose takes most of the abuse to minimize wear to the body of the bar. Power Match bars are recommended for 3.5 cu. in (58 cc) and larger saws.
