Abstract: The present invention relates to a temporary electrical service support system including leg members, having a rectangular cross-sectional configuration which can be effectively supported in a stable upright position during use at a construction site by a novel self-contained bracket means without the use of supplemental attachment means. The system of this invention further includes a self-contained bracket member comprising a plate means having a plurality of rectangularly shaped slots located about its periphery for receiving and securing a plurality of leg members therewithin. Centrally located, joined to, and extending from the plate means is stabilizing block means. The sides of the block means are in substantial engagement with the adjacent inner sides of each of the leg members.

Abstract: The present invention is directed to an adjustable adapter system capable of supporting and maintaining a temporary electrical service above ground level at a building site prior to installation of permanent electrical services. The adjustable adapter system is employed in conjunction with respective vertical and bracing support members for maintaining and supporting the vertical member in a uniform, stable, substantially vertical position regardless of the contour of the underlying terrain. The subject system comprises a bracket support means which is easily connected to and adjustably movable along a vertical support member secured to the ground. The bracket support means is movable in an upward and downward substantially vertical direction to a desired position along the vertical support member for maintaining and supporting the vertical member in a uniform, stable, substantially vertical position regardless of the contour of the underlying terrain.
