A popular tool for commercial jobs! Combines safety with a smooth professional finish. The 6″ long heavy-duty stainless steel blade moves smoothly through concrete. This groover creates four 1/4″ deep grooves 3/4″ apart on center while creating an 1/4″ radius edge to prevent chipping from wear. These parallel lines provide a safety tread effect on high traffic areas such as driveways, sidewalks and stairs. The 4-1/2″ wide tool provides thorough coverage on steps, sidewalks, driveways, and slabs. The first groove sits back 1-1/4″ on center from the radius edge. A full top-plate provides additional strength to move through the cement with ease. A steel mounting welded to the top plate attaches the ProForm? soft grip handle. The enhanced texture on the handle reduces fatigue and provides a great grip even when wet.
