A fall protection apparatus includes a single longitudinally extending rigid rail onto which two laterally spaced apart moveable lanyard anchorages are mounted. The rail has a generally H-shaped cross-section with opposing vertically oriented first and second tracks laterally spaced apart by a connecting member extending between the tracks and substantially continuously along the length of the tracks The apparatus is attached to a structure by a support member, such as an overhead or lower support member, with the support member being attached to an upper or lower surface of the connecting member respectively. Each anchorage is adapted to be independently moveable along the length of one of the tracks, with the tracks being sufficiently spaced apart to permit the anchorages to freely pass by each other and the attachment point.
