The stepladder duty rating that supports a maximum of 375 pounds is Type IAA, which is classified as "Special Duty." This category is designed to accommodate the heaviest loads in various professional and industrial applications. The Type IAA ladders are built with materials and construction techniques that ensure they can safely support workers and their equipment, significantly exceeding the requirements of lighter duty ratings.

In contrast, the other types of ladders support lower maximum weights: Type I (Industrial) supports up to 300 pounds; Type II (Commercial) supports up to 225 pounds; and Type III (Light Duty) is rated for up to 200 pounds. Understanding these categories allows workers to select the appropriate ladder for specific tasks, ensuring their safety and compliance with industry standards.
