Abstract
A fixed ladder has a first plurality of parallel rungs arranged along a lower section thereof and also has a walk-through section with vertical side rails arranged at the top thereof. A second plurality of parallel rungs is arranged along the walk-through section. This second plurality of rungs is attached at one end to the vertical side rails of the walk-through section and is easier to hold then the vertical side rails if a foot or a climber slips near the top of the ladder while mounting or dismounting at the walk-through section.
