摘要： 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.

摘要： A ladder upon which a user climbs having a first rail. The ladder having a second rail. The ladder having rungs attached to the first and second rails upon which the user steps. The ladder having a first leveler attached to the first rail. The first leveler having a foot peg and a latch. When the user presses on the foot peg and the latch with the user's foot when the leveler is in an extended state, the first leveler moves into a retracted state. The ladder having a second leveler attached to the second rail. A method for a user to use a ladder. The method has the step of the user pushing with the user's foot against a foot peg and latch of a first leveler to cause the first leveler to move to a retracted state relative to a first rail of the ladder in which the first leveler is. There is the step of the user pushing only against the foot peg but not the latch with the user's foot when the leveler is in the retracted state causing the first leveler to move to an extended state relative to the first rail and be maintained in the extended state. A leveler which positively prevents inadvertent retraction of the leveler from an extended state to a retracted state. A ladder having a module with a first and second ladder leveler.

摘要： A roof anchor including a mounting portion including a plurality of holes formed therein and an anchor portion having an opening formed therein. The mounting portion and the anchor portion are planar members arranged substantially perpendicular with each other. The anchor portion is disposed along one side of the mounting portion with a bend portion formed at an intersection of the mounting portion and the anchor portion. The mounting portion and the anchor portion form a monolithic piece. The opening includes a lower edge and an upper edge, wherein the lower edge is closer to the mounting portion than the upper edge, and wherein a length of the lower edge is greater than a length of the upper edge.

摘要： A stepladder includes a front section having a first front leg and a second front leg. The stepladder includes a step attached to the first front leg and the second front leg. The stepladder includes a latch engaged with the step. The stepladder includes a rear section having a first rear leg and a second rear leg and a cross bar attached to the first rear leg and the second rear leg. The rear section is pivotably attached to the front section. The rear section has a first stud which extends from the first rear leg toward the second rear leg and separate and apart and not in contact with the second rear leg and not in contact with the cross bar. The latch is engaged with and latched to the first stud to define an engaged position where the first front leg and the first rear are in an open position and form an inverted v shape and are prevented from folding together, and the latch when pulled up from the engaged position, disengages from the first stud and allows the front section and rear section to fold together into a closed position where the first rear leg and the first front leg are in parallel. A method of positioning a step ladder.

摘要： A climbing apparatus that rests on a surface includes a flip ladder that can move between a straight configuration and a stepladder configuration. The apparatus includes a tray having a plane attached to the flip ladder that moves with the flip ladder between the straight configuration where the tray plane is essentially parallel with the ladder in a stowed position and a stepladder configuration where the tray plane is essentially parallel with the surface in an open position. A method for climbing includes the steps of moving a flip ladder between a straight configuration and a stepladder configuration. There is the step of moving a tray having a plane attached to the flip ladder from a stowed position where the tray plane is essentially parallel with the ladder to an opened position where the tray plane is essentially parallel with the surface. There is the step of moving the flip ladder from the stepladder configuration to the straight configuration which causes the tray to move automatically into the stowed position.
