Abstract: An anchor is provided for securing the upper extremity of a bunk ladder to an elevated support. A bracket is attached to the upper extremity of the ladder and has a configured hook extending downwardly and outwardly. A socket attached to the overhead support has an overhanging lip and a shoulder located therebeneath and spaced therefrom. The bracket hook is inserted between the lip and shoulder which together vertically immobilize the bracket and prevent withdrawal of the bracket hook therefrom when the foot of the ladder is in a supporting position.

Abstract: A ladder is provided for use with a recreational vehicle in which step treads are formed in two parts. The treads are divided generally along a plane defined by the disposition of the upright ladder rails. The two parts of the stair treads are positioned on either side of the rails and are clamped together in interlocking fashion by means of engageable arms on each step portion which extend toward each other to latch together. Positioned on the upright ladder rails, the ladder steps are securely attached thereto by means of self tapping screws which pass through the opposing step sections and through the ladder rails to sandwich the ladder rails between the step sections.
