Get the height you need to complete the job with a 4-Step Rolling Ladder. Narrow enough to fit through a standard door frame, this 4-Step ladder can go anywhere to help you pick orders, manage inventory, or just reach the top shelf with ease! No need to tilt and roll this ladder to maneuver it around your warehouse; four wheels allow you to move it with just a push. The ladder locks down when in use, which prevents it from moving. Side rails and step tread add extra safety to help you finish the job. Made from tubular steel, this ladder has a weight capacity of up to 450 pounds
