Abstract
A lightweight ladder includes a vertical member of flat sided tubing, rungs formed of angle metal, and ladder feet adapted to engage retaining clips mounted on a vertical structure. The ladder feed are designed to provide wedging between the clips and the vertical structure such that set screws are not required to keep the ladder in place and stable.
