1. Apparatus for stabilizing a work platform extending between first and second ladders, comprising:
a first platform attached to a first ladder, the first platform having a first side plate having first and second notches formed therein, each of the notches being vertically oriented and having an open upper end and a closed lower end, and a locating block attached to the first side plate;
a second platform attached to a second ladder, the second platform having a second side plate having first and second notches formed therein, each of the notches being vertically oriented and having an open upper end and a closed lower end, and a locating block attached to the second side plate;
a work platform having opposed first and second end plates, each of the first and second end plates of the work platform having first and second connecting posts extending therefrom, wherein each of the first and second end plates of the work platform further have a pair of spaced apart guide blocks defining a guide slot therebetween adapted to receive a corresponding one of the locating blocks;
wherein the work platform is adapted to be connected to the first and second platforms with the respective first and second end plates of the work platform facing the respective first side plate of the first platform and second side plate of the second platform, the locating blocks configured for sliding downwardly into the guide slots, and ends of the respective first and second connecting posts of the first and second end plates of the work platform sliding downwardly into the respective first and second notches of the first and second plates of the first and second platforms such that the ends of the connecting posts are supported by the closed lower ends of the notches and can be removed therefrom by lifting the work platform and sliding the ends of the connecting posts upward through the open upper ends;
wherein each locating block is received in the corresponding guide slot with sufficiently close tolerance to prevent axial rotation of the work platform relative to the first and second platforms.
