Abstract
A safety ladder cage system is of a fabricated construction to reduce the time and expertise to provide a safety cage to one side of a scaffold system access ladder. The safety cage system is divided into two components each of which can be carried by a worker to the appropriate point and loosely hung from a ladder rung or the ladder uprights. The worker is then free to accurately position the safety cage component to one side of the ladder. The second component is then brought into position and attached to the opposite side of the ladder in a similar manner. The components are then attached to each other along vertical securing edges outwardly spaced from and generally centered on the ladder. Each component preferably includes its own captured connector for engaging the opposite component.
