Abstract
Ladders have first and second assemblies with pairs of rails that form a pair of hinges rotatable about a pivot axis. The hinges include at least one retainer movable between axial positions along the pivot axis. The at least one retainer includes a body and a support arm coupled with the body. The arm can be pivotable relative to the body between a deployed position and a collapsed position. The support arm can support objects while a user is in an elevated position on the ladder.
