Abstract: A collapsible ladder cage segment having an upper and lower end for attachment to a ladder. The cage segment including at least one rigid support member positioned proximate the upper end of the cage segment and a plurality of flexible support members. The rigid support member and the plurality of flexible support members are substantially in spaced parallel alignment with other. A plurality of flexible longitudinal members are positioned in spaced relationship around the circumference of the support members, substantially normal to the support members, forming a cage-like arrangement. Securing assemblies are on at least one rigid support member for securing the rigid support member to a portion of the ladder so as to secure the segment to the ladder. The unsecured ladder cage segment is capable of collapsing for transportation and storage.
