The Tapepro Outside Corner Roller is designed to be used on a variety of 90 degree outside corner beads including Trim-Tex, No-Coat, Award, etc. Features a stainless steel body with acetal rollers and bushings. A very special and exclusive feature of this Corner Roller is that the rollers pivot in the center. This helps to bead precisely, even on angles that are not at an exact 90 degrees. Corner beads that have either tapered or parallel legs become a lot easier to set with this roller versus others like it. The OCR can be fitted to a standard Tapepro, Blue Line USA Handle or Pro-Reach Extendable Handle.
