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. 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. Bolt down in permanent applications, or use as a mobile entrance mat for workers who toil in muddy 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. Simply shake the dirt off or spray off with a hose.
