Abstract
A portable work platform for use in the construction trade which includes a pair of side rails interconnected by a plurality of crossbars and supported by pivotal legs connected to the rails. Disposable edge runners are attached along the upper surface of each rail to protect the rails and crossbars from damage caused by cutting and machining material on the platform surface. In addition, the cross-bars are of a square cross-section to enable workpieces and tools to be clamped to the bars for support.
