Abstract
Abstract Top end caps are fixed to side rails of a ladder, each end cap having a pair of linearly aligned longitudinal slots therein, each slot having a closed upper end and an enlarged entrance at its lower end. A spring loaded latch is provided at the entrance of the lower slot and normally closes the entrance, but is resiliently deflectable to open the lower slot entrance and admit the lug of an accesssory, to thereupon return to closing position and preclude separation of the accessory from the cap assembly. Various accessories are provided with end lugs and shafts extending therefrom and spanning the space between side rails by rigid or flexible means, to facilitate various types of positioning of the upper ends of ladders.
