摘要： A LADDER, MEMBER FOR CONNECTING A RAIL TO A HORIZONTAL ELEMENT OF A LADDER, AND METHOD, AND APPARATUS AND METHOD FOR HOLDING A WASHER A member for connecting a rail to a horizontal element of a ladder. The member comprises a first portion that connects to the horizontal member. 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 placinga 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.
