6"x 5-1/2" Stainless Steel Safety Walking Groover has a 6" long heavy-duty stainless steel blade that moves smoothly through concrete driveway and sidewalk. This groover creates six 1/4" deep grooves 3/4" apart on center. These parallel lines provide a safety tread effect on high traffic areas such as driveways, sidewalks and stairs. The 5-1/2" wide tool provides thorough coverage on sidewalks, driveways, and slabs. The edges of the tool are turned up to prevent build-up on the tool. A full top-plate provides additional strength to move through the cement with ease. A 360° swivel bracket provides the versatility to let you work from any angle. The wingnut on top tightens the bracket to hold the angle. Use with a Narrow Clevis Handle or handle adapters for use with bull float extension handles, all sold separately. Proudly made in the USA.
