4x10 entrance mats help to provide a safe walking surface while scraping shoes clean. Use 4 x 10' carpet mats made with a nylon or olefin fiber for the best moisture control. For outdoor mats, scraping action is desired. Use a 4x10 floor mat made with polypropylene fibers with an aggressive surface pattern for optimal performance. Entrances with a 4x10 scraper mat followed by a 4x10 carpet mat will serve to remove approximately 75% of the dirt and moisture from shoes BEFORE it can be tracked inside your facility.
