The Mud Chucker is incredibly effective when used where shoes or boots are exposed to dirt, grass clippings, snow, salt, sand or any type of muck that is better left outside. It's designed to scrape dirt, snow, grass clippings or any other muck off the sides of boots or shoes. The pliable rubber finger-tips on its side walls quickly remove the extra gunk before it can be tracked inside. Use it in conjunction with a traditional entrance mat in really challenging areas, or as a stand-alone product in tight spaces. Designed to be bolted or staked down in permanent applications, it also functions as a mobile entrance mat for workers who consistently toil in muddy or messy areas and then travel to the next location. Similar products with stiff coir bristles get clogged with gunk. But the Mud Chucker is easily cleaned. Dirt and debris are easily shaken or hosed off, while snow and ice melt filters down the front and back edges.
