ABSTRACT:
A scaffold joint for connectng the ends of horizontal scaffold members to vertical scaffold members. Spaced pairs of ring support members are fastened to the vertical scaffold members by welding or other suitable means. End connector assemblies are fastened to the ends of the horizontal scaffold members. Each of said end connector assemblies includes an end connector member and a locking member slidably mounted thereon. Each end connector member has a pair of ring engaging portions adapted for engagement with the spaced ring support members on said vertical scaffold members. The locking members are adapted when moved to their locked position to make tight wedging contact with a ring support member, thereby causing the ring engagement portions on the end connector members to be forced into tight engagement with the ring support members to thereby lock the horizontal scaffold members to the vertical scaffold members.
