The 8″ long special brushed stainless steel blade moves smoothly along the edge of concrete slabs. The high quality #18 gauge metal ensures an extra smooth working surface for a quality finish. This edger creates a 3/4″ radius on the edge of concrete slabs to prevent that edge from chipping with wear. The lip extends down 7/8″ for even coverage along ends and forms. The 8″ square tool provides the perfect amount of coverage on sidewalks and projects large and small. An electronically welded back plate provides a place for four rivets to secure the bracket base to the edger. The bracket is designed to adjust 180° degrees to go back and forth along the cement. The toothed bracket tightens to set and keep a desired angle. The bracket and socket is made of cast aluminum for long wearing use. Use with button bull float extension handles, sold separately. Use with a button bull float handle adapter for more versatility.
