Abstract: An extension ladder assembly is provided. The extension ladder assembly comprises a base section having a pair of base section rails and a plurality of base section rungs mounted between the base section rails and at least one fly section having a pair of fly section rails and a plurality of fly section rungs mounted between the fly section rails. At least one rung lock is secured to at least one of the fly section rails and selectively, releasably positionable about at least one base section rung to inhibit movement of the fly section in a generally downward direction. A latching member is rotationally mounted to each rung lock with the latching member selectively movable from a released position to a tensioned position. A biasing mechanism biases the latching member into the released position wherein in the released position, the latching member contacts the same base section rung as each corresponding rung lock.
