A step ladder is designed to hang on an OEM ladder on a recreational vehicle (“RV”) while traveling on the road. The step ladder comprises a hanger bracket to hang the step ladder on the OEM ladder. The bracket is wider than a width of the legs of the step ladder to project over a rung of the OEM ladder. A hook on the bracket grabs the rung of the OEM ladder. The step ladder may be further secured to the OEM ladder by inserting a lock through the bracket and through or adjacent to the rung of the OEM ladder, or by inserting a lock through another rung of the OEM ladder and a retaining tab of the step ladder. A stabilizer attached to the step ladder and the RV can further stabilize the ladder when desired.

A ladder comprises a front leg and a rear leg connected by a slider bracket. The slider bracket comprises a base and a track. The base comprises an aperture therein. The track extends away from the base and comprises a slot therein. The base is rotatably coupled to the front leg by a front pin in the aperture. The track is slidably coupled to the rear leg by a rear pin in the slot. When spreading the rear leg away from the front leg, the base pivots around the front pin as the rear pin slides in the slot of the track until the rear pin reaches the end of the slot in the track. The slot also may include a latch at the end of the slot that engages the rear pin.

Embodiments of a packable ladder and a method of assembling it are disclosed. The packable ladder includes two mainframe tubes and at least two steps. Each mainframe tube has a curved end and an attachable end opposite to the curved end. Each step is shaped as a disk having a first end portion and a second end portion disposed at opposite ends thereof. Each of the first end portion and the second end portion is configured to be attached to a respective one of the two mainframe tubes. The method has two steps. In the first step, each of two side rails is formed by attaching each of two mainframe tubes to one or more extension frame tubes. In the second step, at least two steps are attached to the two side rails at a first end portion and a second end portion of each step.

A ladder safety lock disclosed herein includes a rod adapted for insertion through a ladder rung and at least one hinged flap attached an end of the rod that is configured for attachment to a free-standing secure structure, such as a portion of a roof or wall.

A self-contained knotless security device and method for adjustably securing rope-style pilot ladders and debarkation ladders from any rung to ship deck lashing points, the device not relying on additional mechanical fittings or knot-tying skills. The device comprising a section of multi-strand polyester rope comprising an integrated polyolefin core and having a ship end and a ladder end, the ship end comprising a rugged, wear and corrosion-resistant thimble eye or shackle and the ladder end comprising a flexible long soft eye on the other end. The method comprising encircling ladder suspension members with the device and securing the device to the ship deck lashing point. Alternate polyolefin core construction provides tailored performance characteristics.

A ladder standoff includes at least one bent plate that is configured to be detachably engaged with at least one ladder rung of a ladder by at least one connection plate that is configured to be detachably connected to the bent plate and to the ladder rung. The ladder standoff may be attached to a ladder and used to secure a ladder to a vertically-extending building wall structure at a selected distance. The length of the ladder standoff can be extended in a substantially horizontal direction in relation to the vertically extending ladder and vertically extending building wall to provide a ladder standoff with variable lengths to accommodate different distances between the ladder and the surface of the vertically extending building wall.

A ladder safety device configured to be secured to the edge of roof to prevent a ladder leaned against it from sliding sideways or falling away from the roof edge. The ladder safety device comprises a generally flat, planar inner body portion comprising a first inner horizontal rail and vertical rails spaced from one another to define a plurality of large hand-grip openings between them. The ladder safety device further includes an outer body portion comprising a second horizontal rail spaced vertically from the first horizontal rail and connected thereto by outer portions of the vertical rails. Fastener holes formed along inner ends of the vertical rails can be used to secure the device to a roof, and projecting outer fingers define a ladder recess on an outer edge of the outer body portion. The ladder safety device is installed with the outer horizontal rail and portions of the vertical rails and the hand-grip openings spaced outwardly from the roof edge to provide a hand grip.

A system includes a clamp that includes a first arm, a second arm, and a threaded rod coupled to the first arm and the second arm. The threaded rod is configured to be substantially vertical when the clamp is clamped to the static structure. The clamp is configured to, while the user on a ground surface and in response to the nut being rotated about the threaded rod, a first jaw is urged towards a second jaw such that the static structure is clamped between the first jaw and the second jaw. The system further includes a first bracket configured to be releasably affixed to an upper portion of a first side rail of a base station of an extension ladder, and a second bracket that is configured to be releasably affixed to a lower portion of the first side rail of the base station of the extension ladder.
