ABSTRACT:
Adjustable 3-way scaffolding fasteners for holding together four corners of a scaffold with four upright members, two first cross members with extremes, and two second cross members with extremes. The fasteners include a pair of right fasteners and a pair of left fasteners. Each fastener of the pair of right fasteners connects one extreme of the extremes of one cross member of the two first cross members and one extreme of the extremes of one cross member of the two second cross members to an upright of the four upright members of the scaffold, and are separate and diametrically opposed to each other when being used. Each fastener of the pair of left fasteners connects the other extreme of the extremes of the one cross member of the two first cross members and the other extreme of the extremes of the one cross member of the two second cross members to another upright of the four upright members of the scaffold, and are separate and diametrically opposed to each other and opposite to the pair of right fasteners when being used.
