The member also comprises a second portion which connects to the rail and extends essentially in parallel with the rail. The second portion is integrally connected to the first portion such that the first portion and the second portion are one continuous piece. The second portion is in an angular relationship of less than 90.degree. with the first portion. A member for connecting a rail having a first rail flange and a second rail flange to a horizontal element of a ladder. The member comprises a first arm which connects to the first rail flange and the horizontal member. The member is also comprised of a second arm which connects to the second rail flange and the horizontal member. Additionally, the member comprises a central body which is integrally connected to the second arm and the first arm. The first arm, second arm and central body are one continuous piece, preferably of plastic. A ladder comprised of the member for each rail. A method for using a ladder. The method comprises the steps of placing a load on the ladder. Next there is the step of transferring forces generated from the load to a member connected between a rail of the ladder and a first step of the ladder.

The method comprises the steps of placing a load on the ladder. Next there is the step of transferring forces generated from the load to a member connected between a rail of the ladder and a first step of the ladder. The member can include an apparatus for holding a washer. An apparatus for holding a washer. The apparatus comprises a backing having a backing surface. The apparatus also comprises a retainer extending from the backing. The retainer holds the washer. The retainer has a front through which the washer is introduced into the retainer. Additionally, the apparatus comprises a stop extending from the backing. The stop is disposed adjacent to the front of the retainer and prevents the washer from coming out of the retainer when the washer is in the retainer. The present invention pertains to a method for holding a washer. The method comprises the steps of positioning the washer at a front of a retainer. Then there is the step of moving the washer past a stop adjacent the front of the retainer. Next there is the step of seating the washer in the retainer, with the stop preventing the washer from coming out of the retainer.

    摘要: A ladder shoe for providing enhanced stability between a ladder and a variety of surfaces. The ladder shoe is comprised of a shoe body having a first side plate, a second side plate and a base. The first side plate and the second side plate are attached to the base. The side plates include curved slots through which a fastener is disposed which movably connects the ladder shoe to the end of the ladder's side rail, thereby allowing the ladder shoe to move between a first position where the base is at a first angle with respect to the side rail and a second position where the base is at a second angle with respect to the side rail. Each slot has a notch in which the fastener catches causing the shoe to be maintained in an intermediate position until the shoe body is desired to be placed into another position. The base has a bottom which provides a slip resistant surface for engaging the shoe body to essentially flat surfaces when the shoe body is in the first position. Preferably, a spur plate is provided for engaging the shoe with penetrable surfaces when the shoe body is in a second position extending from the base. There is also a method and system involving the same.
