This bed plug/puck system is designed to fit the factory fifth wheel hitches on 2014 - 2022 Dodge Ram trucks.  They are made in the USA of stainless steel and designed to outlast the truck.  Once installed, the plug system keeps debris or cargo from falling into the fifth wheel hitch points.  With the inserts installed, the system is flush with the ridges of the bed and does not hamper loading or unloading of cargo.
