To use, slide an edge of a dry mat into the slot and the spring-loaded grip will lock onto the mat instantly. To release the mat, push the lever forward. This tool is easy to use, keeps you clean, and prevents you from fighting with stall mats (which, let's be real, is usually a losing battle). This tool is also convenient for moving plywood and carpet. The Grabbit Mat Mover adjusts for mats up to 3/4" thick. This tool is a barn essential and will come to your rescue when you need it most!
