A pair of hooks are located such that each hook is positioned adjacent and upper end of an associated rail. A securing apparatus is coupled adjacent the upper end of the first pair of spaced apart rails. The securing apparatus includes a pair of spaced apart engaging members and may include a cross-member coupled therebetween. Each of the engagement members is pivotal with respect to an associated rail of the first pair of spaced apart rails. In one embodiment, the securing apparatus lacks any biasing members (e.g., springs or actuators) or locking members. The engagement members and hooks cooperatively encircle and overhead, generally horizontal support member to support and secure the ladder in a desired position.
