3M Scraper Mat, 4'x6', Slate Scraper matting is designed for outside medium traffic entrance areas with up to 400,000 people per year. Backed vinyl loop matting for foyers, recesses well in areas. Vinyl loops scrape dirt and moisture off shoes, allowing it to fall into the mat and not be tracked into the building. Durable vinyl performs even in extreme temperatures from -10 degrees F to 150 degrees F (negative 23 degrees C to 65 degrees C). Doesn't fade when exposed to sunlight and doesn’t absorb water.
