Abstract: A modular framing system having a plurality of framing units between which panels may be retained. Each framing unit includes a main body having a plurality of circumferentially spaced receiving chambers having semi-circular configuration. One or more panel retainers may be connected to the main body, each including a panel cup and a chamber rod. The chamber rod is a which may be lowered into one of the receiving chambers to connect the panel retainer to the main body. The chambers have an angular extent less than that of the chamber rods, such that the rods and panel cups may be rotated to the desired angular position with respect to the main body. Each of the panel cups is adapted to receive a lower corner of a panel. With this arrangement two frame units may be located at spaced positions, with the panel cups of associated panel retainers opening towards each other to support the panel. The framing units may include a stake for driving into the ground.
