Retractable ladder
A stretchable ladder, having inner leg bar and outer leg bar, the side edge of the outer leg bar forming an opening. The outer leg bar is sleeved on the inner leg bar, with the inner leg bar and the outer leg bar being relatively slidable. The ladder has a lock structure for locking the inner leg bar and for preventing the inner leg bar from separating from the outer leg bar. The lock structure is disposed at the outer leg bar, and is hookable to the inner leg bar, so as to make the inner leg bar embedded in the outer leg bar.
Ladder, overmolded foot and method
A ladder having a first rail having a bottom and a web, a first flange attached to a first end of the web and a second flange attached to a second end of the web. The ladder having a second rail. The ladder having rungs attached to the first rail and second rail upon which a user steps to climb the ladder. The ladder having a foot having a plastic body with a recess which receives the end of the first rail and is positioned about and conforms to the web and the first and second flanges of the first rail. The foot has a plastic base having a top side from which the body extends. The base has an edge positioned about the body with perforations, and a rubber tread disposed along a underside of the base and extending through the perforations and along the edge on the top side of the base to form an overmolded portion of the tread that attaches the tread to the base without any mechanical or other types of fasteners. The rubber tread forms a bond with the underside of the base and the edge on the top side of the base. The foot for a bottom of a rail of a ladder. A method for placing a ladder. A method for producing a foot for a bottom of a rail of a ladder.

LEVELING AND STABILIZING ACCESSORY FOR LADDERS
Described herein is an improved ladder leg extender and leveler assembly including an elongate frame member or structure which can be fixed in a flush relation to a ladder leg side rail and secured to at least two ladder rungs. Each elongate frame member includes a slidably engage elongate leg extension which engages a height adjustment member or actuator that is located on a surface of the elongate frame member. The height adjustment member operates via a spring actuated pin or rod which engages a series of pre-set slots on the elongate leg extension to adjust the height of the ladder on either side. Also, a pivoting ladder stabilizing element which is extendable. This greatly provided additional stability and security.
LADDER STABILIZER APPARATUS
A stabilizer apparatus has a mounting frame that mounts onto a ladder so as to be longitudinally slidable along the rails of the ladder. Stabilizer legs are pivotally supported on the mounting frame between a stored position in which the legs are supported alongside the mounting frame and a working position protruding outwardly from the mounting frame. A screw clamp type retaining mechanism selectively prevents longitudinal displacement of the mounting frame relative to the ladder for stabilising the ladder while in the working position of the legs.

Ladders, ladder components and related methods
Ladders, ladder components and related methods are provided including various embodiments of a combination ladder. In some embodiments, a platform is provided that is fixedly coupled with a rail assembly of a combination ladder. The platform may pivot between a useable position or state and a stowed or stored position or state. The platform may maintain a position relative to certain rungs of the rail assembly while being displaceable relative to other rungs of the rail assembly. A hand rail may be coupled to the rail assembly and a tray may be coupled with the hand rail. The tray and the platform may be configured to maintain a constant distance between one another while the rail assembly is adjusted for height.
