Climbing Product Having an Extendable Section Lock Assembly, and Methods for Using and Producing a Climbing Product
A climbing product whose sections are extendable having a base section and a fly section. The fly section in sliding engagement with the base section. The climbing product has a lock assembly having a lock fly portion directly attached to the fly section. The lock fly portion directly engages with the base section to lock the base section with the fly section. The lock fly portion has a plunger. The lock fly portion disengages from the base portion by moving the plunger. A method for using a ladder whose sections are extendable. A method for constructing a ladder whose sections are extendable.

EXTENSIBLE LADDER
An adjustable-height ladder includes left and right legs and a series of horizontal steps coupled to the left and right legs. The ladder also includes a utility tray.
Ladder extension brake
Provided is a braking system for use with an extension ladder having a base section and a fly section movable relative to the base section via an adjustment rope. The braking system includes a bracket for attachment to the fly section. A pulley and an arm are secured to and movable relative to the bracket by the adjustment rope between a first position when no tension is applied to the rope and a second position when tension is applied to the adjustment rope. A cam is movable between an engaged position when the pulley and arm are in the first position with the cam engaging with the base section to prevent movement of the fly section relative to the base section, and a disengaged position when the pulley and arm are in the second position.

LADDERS, LADDER COMPONENTS AND RELATED METHODS
Ladders, ladder components and related methods are provided. In some embodiments, adjustable stepladders are provided which include locking mechanisms that enable height adjustment of the ladder through application of a force towards the rails of the ladder. In other embodiments, spreader mechanisms are provided with cross bracing located and configured to provide additional stability to the ladder while also incorporating a handle that enables efficient collapsing of the ladder while reducing the potential of pinching ones hands or fingers. In another embodiment, a device is provided for selective coupling with the ladder that includes a support or safety rail and an adjustable tray. The device may be coupled with the ladder in a number of different positions including a stowed position. In another embodiment, a hinge assembly is provided having a magnetic component configured to be magnetically coupled with and temporarily store an object on the ladder.

STEP STOOL WITH MOVEABLE HANDRAIL
A step stool includes a step frame including a plurality of legs and a handrail coupled to the step frame. The step frame is foldable so as to assume a flat profile for storage. The handrail is mounted on the step frame and is movable relative to the step frame. The handrail provides support for a user standing on the step frame.

Ladder stabilization support assembly
A ladder stabilization support assembly for lateral and vertical stabilization support to ladders in general and long span extension ladders in particular preventing the ladders from lateral movement such as tipping, overturning or slipping off the supporting grounds. The assembly is built to take advantage of a light-weight t-slotted aluminum profile and comprises two telescopic support legs pivotally mounted on opposite sides of a ladder to effectively support and level the ladder on any uneven supporting grounds. An adjustable sliding mechanism provides for a smooth, low tolerance and wobble-free telescopic sliding function with numerous length adjustments positions. A pivot joint provides for endless number of pivotal and swivel adjustment positions. The assembly can quickly and easily be mounted onto the ladder, remain permanently attached to the ladder or be taken off the ladder when not in use. The assembly also allows extension ladders to operate in a self-supporting stand-alone mode.
