Werner 28 ft. Fiberglass Extension Ladder is an extra heavy-duty professional use ladder designed for safety and durability. It features external guides at the top of the base section that securely interlock rails, providing added stability. The base and fly sections separate easily, allowing the base section to be used as a single ladder. Internal guides on the bottom fly section also securely interlock rails to ensure safe operation. The ladder is equipped with slip-resistant Traction-Tred 1-1/2 inch flat D-rungs for secure footing. It includes a durable rail shield bracket and shoe with Shu-Lok slip-resistant pad and spur plate, along with the exclusive Alfo rung joint that delivers twist-proof safe performance. The rails are made of electrically non-conductive fiberglass in a bright orange color for visibility and safety. This ladder also includes a rope and pulley system for easy extension and retraction. Note that fiberglass ladders should not be stored in direct sunlight as ultraviolet rays can weaken the polyester resins over time. The Werner 28 ft. Fiberglass Extension Ladder supports a load capacity of 300 pounds and meets Type IA duty rating standards, making it suitable for demanding professional applications. Model Number: D6228-2
