ABSTRACT:
A scaffold support comprises a beam fabricated in the form of a rectangular steel tube having width less than its height, and a pair of legs each fabricated in the form of a rectangular steel tube. The legs are welded to opposite sides of the beam so as to diverge from one another at an acute angel and so as to angle outward and downward from the beam at an acute angle from the vertical when the beam is oriented horizontally. An angle bar welded to each leg and extending between the legs to stabilize the legs and to provide a step. A steel scaffolding retainer welded to an outer end of the beam and extended above a top edge of said the so as to prevent scaffolding from moving beyond the outer end, and a steel mounting plate is welded to an inner end of the beam so as to provide a bearing surface for the inner end. Lumber leg extensions may be inserted into the legs to provide an elevated scaffolding support surface, and the lumber leg extensions may be fitted with cross members to provide a ladder, with the last step of the ladder being provided by the angle bar.
