The Little Giant Sure Step — Built for Professionals Who Can't Afford to Compromise. When your work demands more than a standard step stool can deliver, the Sure Step is ready. Rated ANSI Type IAA at 375 lbs, this 3-step fiberglass step stool is engineered for the extra heavy-duty demands of construction, electrical, HVAC, facilities maintenance, and any job where stability and safety are non-negotiable. Fiberglass rails make the Sure Step naturally non-conductive — a critical advantage when working near live electrical sources. The wide, slip-resistant steps provide confident footing at height, while the lightweight 11.5 lb frame means you can move it effortlessly between work areas without slowing down. Little Giant builds every Sure Step to exceed ANSI safety standards, so you get a step stool that works as hard as you do — shift after shift, job after job.
