Personalize your home with a Rolling Ladder Kit featuring a sturdy, solid aluminum rail and our patented Quiet Glide technology. You can easily add convenience and elegance to your library, pantry, wine cellar, walk-in closet, and more! This eye-catching rolling ladder kit will be a trendy centerpiece in your home. The Rolling Hook Tops have only one wheel on the top, so the ladder can be removed easily. When it is not in use, this ladder can be stored on the railing or removed. In the stored position, there is 7 inches from the center of the rail to the top of the ladder. In the climbing position, there is 3 inches from the center of the rail to the top of the ladder and the ladder's rolling wheels are 31 inches from the wall. For an 8 ft. ladder, the center of the rail would be mounted at 91 inches high (from the floor). The horizontal bracket dimensions are 15/16" H x 1-3/4" W x 2-3/8" D with 7/8" CC between bracket hole centers. The vertical bracket dimensions are 2-5/8" H x 23/32" W x 2-3/8" D with 2" CC between bracket hole centers.
