The undergrate stairway access assembly is a portable stairway designed to provide safe access to different levels through temporary openings in supporting surfaces such as floors and sidewalks. Specifically, the undergrate stairway access assembly is an assembly comprising an integrated guardrail and step structure that allows a worker to safely traverse between different levels through openings in the supporting surface while preventing workers from inadvertently falling through these openings. The undergrate stairway access assembly is ideal for providing protection for projects that require the removal of grated surface protections such as sidewalk grates, sewage grates or undercarriage bays. The undergrate stairway access assembly comprises one or more step structures and a guardrail structure.

A swim ladder assembly mountable to, for example, a dock, a raft, a float, or a boat, comprises a pair of side mount members and a swim ladder pivotally mounted between the side mount members. The swim ladder is designed to permit a swim ladder to rotationally pivot about a pivot axis and lock securely at specific orientations is disclosed herein. The pivot axis is positioned to be spaced above the dock surface and be spaced rearwardly from the edge of the dock to which the ladder is mounted so that a user does not have to reach out over the edge of the structure to rotate the ladder. A pin insert system to allow the swim ladder to be stowed in multiple different orientations without fear of free rotation. Arcuate handles at the top of the ladder provide structural support to the ladder as it transitions between orientations.

A ladder assembly is described. The ladder assembly includes a frame, a door, a ladder and a cord manipulation assembly. The frame at least partially surrounds a first opening. The door is movably connected to the frame. The door is configured to cover at least a portion of the first opening of the frame, the door defines a second opening. The ladder is connected to at least one of the frame and the door. The ladder has a first side rail, a second side rail spaced a distance apart laterally from the first side rail, and a plurality of rungs extending between the first and second side rails. The ladder is configured to be at least partially positioned within the first opening of the frame. The cord manipulation assembly is connected to the door. The cord manipulation assembly has a power source connector, a reel adapted to support a cord, a motor operatively connected to the reel and the power source connector, and a remote control transceiver assembly operatively connected to the motor and the power source connector.

A flip-over ladder system includes a handle assembly configured to be mounted to a front face of a wall. The system further includes a ladder assembly, including first and second rail assemblies defining left and right sides of said ladder assembly, at least one rung spanning said first and second rail assembly, first and second bracket members, each configured to be both secured to said front face of said wall, and to vertically support said first and second rail assemblies, respectively. Each of said first and second rail assemblies comprises a bottom rail segment hingedly coupled to a middle rail segment, a middle rail segment hingedly coupled to an upper rail segment, and wherein said upper rail segment is hingedly connected to said first and second bracket member, respectively.

A folding staircase for use in a door opening having a threshold. The folding staircase has a pair of stringers that have an upper end and a lower end that is adapted for contacting a ground surface. The stringers are spanned by at least one tread. A hinge is connected to a floor near the door opening and a threshold plate pivotally connected thereto is movable between a use position and a stowed position. The staircase may be provided with a lifting mechanism that biases the staircase and threshold plate toward their stowed positions. The lifting device provides a variable force that provides more rotational force when the staircase would require a user to bear more of its weight and less force when less of the weight of the staircase would be borne by a user.
