Fifth Wheel Trailer Large Bed Plug

My son has a Ford F350 with fifth wheel connections. The plugs that came with the trailer hitch are two pieces and do not stay in place. This is designed as a single piece with enough material to have it last for a long time even with pallets being pushed across it. I also designed the 4 small plugs that twist in place on another design. Unfortunately this one does not twist into place but seems to stay well even over bumps.Boost MeIf you find this useful, please consider rating the design and boosting it for free!
