The T7406 Fiberglass 6 ft Twin Step Ladder features a duty rating of 375 pounds per side of the ladder. Designed for one or two-person jobs, the T7406 ladder has a heavy gauge aluminum top and features heavy duty internal spreaders to resist damage around the worksite or in transit. The GLAS*MARK® Violater stripes on the rails make the ladder more visible and the Edge® bracing system and external rail shields add to the long lasting durability of these ladders. Fiberglass rails are non-conductive for working near electricity.
