Abstract: A flexible net-like covering for the doorway of a recreational vehicle to prevent occupants or objects from falling through the accidentally opened door. The covering, carried by a roller biased to a rolled condition and positioned above the recreational vehicle doorway, is manually extendable downwardly to cover the doorway. The sides of the covering provide fasteners movably carried in channels positioned on the sides of the doorway to maintain the net in operative position covering the door against applied forces.
