Three Section Extension Ladder and Method
An extension ladder including a base section and an intermediate fly section. The intermediate fly section slidably attached to the base section. The extension ladder including a top fly section. The top fly section sliding attached to the intermediate fly. The extension ladder including a handle having a first strap portion attached to the base section having a first buckle portion, and a second strap portion attached to the top fly section having a second buckle portion that engages with the first buckle portion when the base section, intermediate fly section and top fly section are in a folded state where they essentially form a shape of a cube so the base section, intermediate fly section and top fly section can be lifted by the handle. The present invention pertains to a method of moving an extension ladder.
Ladder Stabilizer
A ladder stabilizer removably mounts to one of the two spaced rails of a conventional ladder, and a mirror image stabilizer preferably mounts to the other rail. The stabilizer is of unitary construction, preferably injection molded from thermoplastic material, and includes a longitudinal member with an open channel along one longitudinal surface, the channel bounded by opposing longitudinal flanges. The member is sized and shaped and of sufficient flexibility to removably mount to the rail at any desired vertical position, and is relatively non-slidable with respect thereto once mounted. An opposite longitudinal surface of the member includes a plurality of step-like serrations. With one stabilizer mounted to each of the two ladder rails, and the ladder leaned against a structure for conventional use, the step-like serrations reduce the risk of movement of the ladder relative to the structure, and therefore promote safe use of the ladder. Also, the composition of the stabilizer protects the structure from any adverse effects.

SYSTEM FOR SECURING AN UPRIGHT LADDER
A system for securing an upright ladder provides a robust and reliable mechanism for securing the ladder to a vertical object such as a pole or tree. The system comprises: a pole bracket positioned adjacent a top distal end of the ladder between a first rail and a second rail of the ladder; an upper anchor mechanism positioned on or adjacent the first rail; an upper ratchet cleat mechanism positioned on or adjacent the second rail; and an eyelet/guider positioned adjacent the upper ratchet cleat mechanism for guiding, in use, a rope into the upper ratchet cleat mechanism; wherein the upper anchor mechanism and the upper ratchet cleat mechanism are positioned at approximately a same longitudinal distance from the top distal end of the ladder.

Extension Ladder and Methods of Making and Using an Extension Ladder
An extension ladder having a base section having a first base rail and a second base rail in parallel and spaced relationship with the first base rail and rungs attached to and between the first and second base rails. The extension ladder having a fly section having a first fly rail and a second fly rail in parallel and spaced relationship with the first fly rail and rungs attached to and between the first and second fly rails. The fly section in sliding engagement with the base section. The extension ladder having a force applicator attached to the base section and the fly section which offsets some or all weight of the fly section. A method for using an extension ladder. A method for manufacturing an extension ladder.
LADDER ASSEMBLY
A ladder assembly for use with a tree or other vertical support includes a first tube and a second tube that is nestable within the first tube. The second tube includes at least one movable step that is movable to one end of the tube to enable almost full insertion of the second tube into the first tube for compact storage and, when the tubes are separated from one another, the movable step is movable to the other end of the tube to provide an ideal step position for a climber. The ladder assembly achieves the same functionality as a telescoping pole but with fewer tube sections because the tubes are separable.
Walkthrough and standoff mechanisms for ladders, ladders incorporating same and related methods
A ladder and ladder accessory are provided including an accessory that may be coupled to the ladder in multiple configurations and serve multiple purposes. In one embodiment, a pair of components are each selectively coupled with associated rails of a ladder in a first, stored state, and a second, walkthrough state. When in the walkthrough state, the components extend upwards from and above the rails so that a user may gasp the components and step between the components when transitioning from the ladder to an elevated surface (e.g., a roof) or vice versa. In another embodiment, the components may be coupled to the ladder such that they extend in a direction that is substantially transverse to a plane through which the rails extend. When in this transverse orientation, the components may be used as a stand-off device.

Adjustment mechanisms, ladders incorporating same 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. The locking mechanism may include a base or bracket, a handle or lever pivotally coupled with the bracket, an engagement pin coupled with the lever, a biasing member to bias the handle towards a first position relative to the bracket, and a detent mechanism for retaining the lever in at least a second position relative to the bracket.
