Also available are fixed dock ladders. These dock ladders come in a top walk through version and a side step version.
Standard fixed and walk thru models can be used up to 20′ without safety cages. OSHA requires safety cages on ladder heights exceeding 20′. Separate cages are offered for updating older ladders to current safety standards.
When you require access to your rooftop, but don't have a rooftop hatch, a fixed access ladder is one of the safest ways to access your rooftop. Many regulations are in place in order to ensure that permanently fixed ladders are safe to use and to ensure they continue to be safe to use for the duration of their lifetime.
