This 30" drive belt is for McLane edgers. McLane edger/trimmers use single lever blade clutch and depth control. Each edger/Trimmer uses an all steel heavy duty chassis along with a tubular steel handle, and is finished with a powder coated-baked polyester paint that resists chipping and corrosion. Best of all, McLane edgers are designed to ride on most curbs while still delivering a clean cut every time.
