Abstract: Described herein are examples of a system which includes a stow box, a base portion, an extension portion and a leg. The stow box forms a three-sided box sized to fit into a cargo space of a vehicle and includes a top surface for storage of items within the cargo space of the vehicle and on top of the stow box. The base portion translates into and out of an interior of the stow box without disturbing the items. The extension portion is pivotably is coupled to a first side of the base portion to lay atop the base portion for translation of the base portion into a stowed arrangement and to extend a surface area of the base portion in a deployed arrangement. The leg applies support to the at least one of the base portion and the extension portion, and displaces for the stowed arrangement.

Abstract: A method of using a reciprocating saw blade having an elongated body with a front body portion and a rear body portion, each having a front end, a rear end, an elongated cutting edge extending between the front and rear ends and a back edge opposite the cutting edge. A first tang that extends from the rear end of the rear body portion may be coupled to a reciprocating saw. The saw blade may be removed from reciprocating saw, and a second tang, which extends from the rear end of the front body portion, may be exposed by breaking off an entirety of the rear body portion in a single integral piece from the front body portion. The front body portion, without the rear body portion, may be coupled to the reciprocating saw by coupling the exposed second tang to the reciprocating saw.

Abstract: A portable staircase for use at construction sites that comprises fold-down railings to facilitate transport from one construction site to the next. The portable staircase includes a plurality of horizontal treads supported by stringers. Handrails are provided which pivotally connect to the stringer utilizing a plurality of handrail support posts. A permanent pivot pin pivotally connects the handrail to each of the handrail support posts. Another permanent pivot pin pivotally connects each of the handrail support posts to the stringer. The handrail can be locked into one of two pre-selected positions: a first folded-down position to facilitate transportation and a second upright position for use at construction sites. Two removable pins may be employed to lock the handrail in position: a first removable pin to lock the handrail support post to the stringer and a second removable pin to lock the handrail support post to the handrail in the up and usable position.
