Abstract: A modular ladder assembly includes at least two ladder assemblies, each assembly having first and second parallel stiles and a plurality of spaced apart rungs disposed between the first and second stiles, the plurality of rungs being perpendicular to said first and second stiles. The first stiles of the at least two ladder assemblies are mechanically connected together and at least one adjustment assembly is mechanically connected to the second stile of one of the at least two ladder assemblies and a second end of at least one adjustment assembly is mechanically connected to a second stile of a second of the at least two ladder assemblies so that the at least two ladder assemblies and the at least one adjustment assembly have a triangular shape when viewed from a plane perpendicular to the first and second stiles of the at least two ladder assemblies.
