Unlike tube squeegees with their belt-sanded round edges, the Grip-N-Glide features a .24" thick squeegee blade with French edges that are machine milled for maximum water extraction. And you can use either the firm yellow 90A or softer orange 85A blade to meet your application needs. The blades fit snugly into a frame that is covered by a substantial hand grip designed with comfortable finger grooves and a special surface texture to provide the ultimate control in either wet or dry use.
