These heavy duty scrapers are widely used for a variety of scraping jobs and are especially useful for removing sponge carpet backing. The angled blade holding heads, plus the razor sharp blades, provide ‘clean shaving’ cutting action. Each scraper has a comfortable vinyl grip and three case hardened screws to resist slot wear and give maximum blade holding power. The No. 690 is the standard 12" long scraper, the No. 790 is the 18" long scraper for tougher jobs and the No. 990 is the 48" long stand-up scraper. Supplied with one blade, installed backwards for safety. Replacement blades are available.
