Extreme Max Hinged Aluminum Trailer Door Slider Plate 72" for enclosed trailer.

Brand new in the box, I have two of them. $138 on Amazon, asking $75 obo each.

Stop getting caught in the gap between your trailer door and trailer bed! The Extreme Max Trailer Door Slider Plate maintains a smooth transition between the trailer and the entry ramp, eliminating the inches-deep gap notorious for catching snowmobile skis or bouncing wheeled toys. The plate mounts directly and permanently to the trailer floor and utilizes a piano hinge to easily fold the plate out of the way when closing the door.
