3M™ Nomad™ 8300 Modular Entrance matting is designed solely for scraping dirt from soles of shoe and can be used for heavy traffic areas, indoor or outdoors. Its scraping surface, with triangular, multi-angle scraping allows optimal dirt removal. The large, open pockets trap and hold the dirt. The large, open 'scraper' profiles, have heel steps to prevent heel trapping. The 300 mm x 300 mm tiles simply clip together, for a secure fit and a good design. The tiles fit into most common recessed wells or can also be surface mounted with Nomad Modular Edging.
