Abstract: The invention is a scaffold access system for use in a scaffold frame of horizontal and vertical scaffold members. The system includes double barrel scaffold horizontal member, a series of short scaffold boards, a series of long scaffold boards, a short vertical scaffold member, a safety gate, and a series of short horizontal members. The double barrel scaffold horizontal member has a upper tube and a lower tube joined in a vertical relationship and a third tube slidable in the lower tube. Each tube has an interior and an exterior end. The upper tube and the third tube have an attachment member positioned on its respective exterior end. The upper tube has an upstanding vertical stub, to which is attached the short vertical scaffold member. The short scaffold boards and the long scaffold boards are placed on the scaffold frame to define a scaffold deck with an access opening.

Abstract: An intermediate scaffold member join comprising a top side, a first side and a second side cooperating to form a channel therebetween. The channel is sized to accept a horizontal scaffold member. The first side has a clamp for attaching to a horizontal scaffold member, the clamp joining a horizontal scaffold member substantially perpendicular to a horizontal scaffold member positioned in the channel. Positioned on the top side is a vertical stub directed away from the channel, where the vertical stub is connectable to a vertical scaffold member.
