Abstract
A modular ladder system has a rung section having two elongate lateral stile extrusions and elongate rung extrusions spanning therebetween. Each stile extrusion may define an attachment side having an attachment face which has two attachment channels which are adjacent, parallel and longitudinally arranged along the attachment face. Each attachment channel may have inward facing rails which define an elongate insertion space therebetween and a relatively wider connector head accommodation void thereunderneath. Furthermore, each rail may define a connector head engaging under edge. Each stile extrusion may further define a connection side adjacent to the attachment side which may define a splice joint extrusion accommodating void therein. In this way, the present modular ladder system may be quickly and easily constructed and various accessories quickly and easily attached thereto.
