A screen panel 15 for mounting to a vibratory screening apparatus that includes a plurality of beams 11 to which screen panels 15 can be mounted. The screen panel 15 comprises a square or rectangular frame 21 including a pair of spaced apart and parallel side frame members 25 and a pair of spaced apart and parallel end frame members 38 connected to the side frame members 25. The frame 21 defines an upper edge and the side and end frame members define a square or rectangular outwardly facing surface. The frame 21 is connectable to a pair of adjacent beams 11 by connectors 20 that connect with the outwardly facing surface of the side frame members 25. The screen panel 15 also comprises a square or rectangular screen 22 connected to the frame 21 which extends over the upper edge of the frame 21 and forms a square or rectangular skirt 33, 36. The skirt 33, 36 overlies the outwardly facing surface of the frame 21 and connects to each of the side and end frame members along the outwardly facing surface to connect the screen 22 to the frame 21. The connection between skirt 36 and the outwardly facing surface of the side frame members 25 is made closer to the upper edge of the frame than where the connection between the connectors 20 and the outwardly facing surface of the side members 25 of the frame 21 is made.
