Abstract
A frame for supporting vertical loads and an aluminum tubular leg for such frame is disclosed. The legs are joined by a brace arrangement and connectors are used for mechanically connecting the brace arrangement to the legs for stabilizing the legs when under load. Each of the legs has spaced portions which are substantially symmetrical about a plane containing the longitudinal axes of the frame legs and which provide areas for mechanical connection of the brace arrangement to the leg. Such mechanical connection of the frame provides a versatile frame which may be used in concrete forming work and which may be readily repaired.
