Stepladders are self-supporting and provide access to elevated areas for construction, maintenance, and utility work. Their legs collapse together to store and transport them around work areas. A-frame and twin stepladders provide convenient access to high areas. Leaning stepladders have V-shaped tops and collapsible legs that allow them to lean against surfaces. Tripod stepladders have a third leg that allows them to balance on uneven surfaces and fit into tight spaces.
