Abstract: In some embodiments, a multipurpose ladder has a first inner section. The ladder has a first articulated hinge and a second articulated hinge. The ladder has a second inner section. The ladder has a first outer section. The ladder has a first locking bar. The ladder has a second outer section. The multipurpose ladder may have a plurality of brackets disposed about outer rails of the outer sections. The brackets provide support to each of the outer rails and strengthens them against bending forces so the rails can be thinner and of lighter weight. The ladder may have an ANSI duty rating of 1 A or an ANSI duty rating of 1 AA.
