The invention provides for a screening panel of a synthetic plastics material which has a screening surface and plug socket connections adapted to secure the panel releasably in a side-by-side relationship with similar panels. The panel includes a spacer element along one peripheral edge of the panel and extending in a direction transverse to the screening surface of the panel and being integral and unitary with the panel so that in side view the panel is substanitally L-shaped. The spacer element is adapted to space the screening surface of the panel from a second screening surface substantially parallel to the screening surface of the panel to thereby form a double screen deck supported on the same support frame.
