Abstract: A concrete anchoring device for a standard nut or bolt, comprising: at least one pair of identical wedge-shaped members aligned in mirror image relationship with their thinnest tapered edges in juxtaposition separated by a distance Y; and adhesive tape spanning distance Y and removably adhered to a substantial portion of the top surfaces of each pair of identical wedge-shaped members; and a method of using the concrete anchoring device to anchor a standard bolt head or bolt nut within a pre-drilled hole.

Abstract: An open wedge socket for a cable or the like includes a wedge having a peripheral surface for engaging the cable, a housing including an outwardly opening channel for receiving the wedge and cable, and an interference member having a sliding fit on the housing to capture the wedge and cable in the channel. The channel provides a first working surface for engaging the cable and the interference member provides a second working surface for engaging the cable. The housing includes shoulders providing first camming surfaces and the interference member includes flanges providing second camming surfaces. When the interference member slides onto the housing it is drawn toward the channel to constrict one end of the channel and capture the wedge and cable between the first and second working surfaces.
