A portable fence system including a snow fence panel having a wood frame of 2''x6'' posts bolted together at the corners, with a 4-foot wide strip of plastic snow fence material pulled taut across the center. Each panel is 8 feet long, with a height of 6'-8'' or 8'-0'', depending upon the application. In both cases the geometry of the frame is optimized for maximum snow trapping efficiency and maximum snow storage, and an opening at the bottom is optimized to eliminate the tendency for snow deposition at the fence. Panels are connected to one another by rebar pins passing through specially designed rotatably mounted U-clips, which also provide attachment to rebar anchors driven into the ground. The U-clip-and-pin connections allow rapid installation and take-down, and add flexibility needed for proper installation in irregular terrain. Panels can be overlapped at either the top or bottom as required to limit space between panels to 11/2'', which improves trapping efficiency.
