12′ Werner Fiberglass Twin Stepladder – Type 1AA (375 lb Capacity)
The 12′ Werner Fiberglass Twin Stepladder is a heavy-duty climbing solution designed for the most demanding professional jobsites. Because this T7400 series ladder features steps on both sides, it allows two workers to collaborate on the same task simultaneously. The elite Type 1AA duty rating supports 375 lbs per side, making it ideal for high-capacity industrial maintenance and commercial construction. We manufacture the tops from heavy-gauge extruded aluminum and secure the rails with non-conductive fiberglass for safe use near electricity.
In addition to its superior strength, this 12-foot twin stepladder includes the EDGE® bracing system to protect against rail damage. The high-visibility GLAS*MARK® Violator stripes make the ladder easier to see in busy work environments. For increased durability during transport and use, this model utilizes heavy-duty internal aluminum spreaders to prevent rail shields from abrasion. Furthermore, the slip-resistant Traction-Tred® steps and padded feet provide maximum traction. This Werner ladder is a professional-grade, OSHA-compliant tool built for safety and long-term durability.
