Crain 704D 5" x 6" Dual Edge Carpet Blade is a hardened, high-carbon steel blade for Crain stripper machines has two 6" long sharpened edges. When one edge of the blade wears out, the other side is still usable, which doubles blade life. Its 5" width produces a blade with some degree of flex that performs well on glued-down carpet removal jobs. A sharp edge is ground to a 30° bevel on both sides. Works on Crain No. 700 or No. 710 stripper machines. Dimensions: 5" wide x 6" long x .079" thick.
