Check Minders or Guest Check Holders are a necessity for the back of the house in restaurants and commercial food service operations. Check Minders come in round order wheels that can be ceiling mounted or free standing. The most popular of all the Check Minders are the lineal straight Check Minders that mount to overshelves or walls. They can be purchased as 12", 24", 36" or 48" lengths. This particular style of Check Minder has marbles or ball bearings that enables the guest check to not only be quickly inserted, but remains secure upon placement.
