Hitch receiver plates typically re-quire grease or a Teflon®disc to minimize friction between the receiver and trailer. The problem arises when a greased receiver hooks on to a trailer with a Teflon®disc. The greased receiver causes a breakdown of the Teflon coated disc. Each time a trailer is switched,depending on what has been used,the receiver plate must be re-coated. This process is messy, expensive and takes time.
