The unique swivel head attachment, designed for the 550 and 5280 Walk-Behind Floor Scrapers, rotates to use the second sharp edge on the razor blade without having to remove the blade. This swivel head is designed to hold any size razor blades. It works on thin, soft coatings, paint, hard-to-remove gummy or other dry adhesives. It is the ultimate for adhesive removal. The swivel-head allows the razor blade to stay in contact with the floor.
