ABSTRACT:
The disclosure relates to scaffolding and includes the use of apertured locking discs adapted to cooperate with vertical supports, and horizontal or diagonal brace members. The ends of the brace members are provided with pivotable locking wedges which can be driven down through said ends and through the apertures in the locking discs. The apertures are all identically shaped and depending upon the intended purpose of the scaffold, certain surfaces of the ends of the brace members and the cooperating apertures are contacted by the locking wedges which thereby determines in which direction the horizontal members will extend.
