Werner AERO Extension Ladder 24′ TYPE IAA Fiberglass Box Rail/Tri Rung

Description

Non-conductive fiberglass box rails eliminate lateral twist during high-voltage line repairs. The Werner AERO Extension Ladder 24′ features slip-resistant Tri-Rungs and a 375-pound capacity. You climb utility poles with rigid confidence. However, this specialized heavy-duty commercial 24-foot extension ladder cannot act as a safe self-supporting step ladder in open rooms.

Werner builds this utility extension ladder with heavy-duty non-conductive fiberglass box-style side rails and slip-resistant aluminum Tri-Rungs. The box rail geometry resists lateral twisting under heavy worker loads. Heavy-duty extruded aluminum locks secure the fly section at specific height intervals. The ladder meets strict Type IAA duty ratings. Protective guide brackets and dual-action feet ensure secure base placement on hard concrete or soft dirt.

Key Features of Werner AERO

Equip your commercial utility crews with this rigid box-rail extension ladder to handle high-voltage electrical drops. Direct wholesale pricing ensures contractors maintain OSHA-compliant climbing gear.

• A 375-pound TYPE IAA duty rating supports heavy workers carrying tool belts up the 24′ span.
• Non-conductive Fiberglass Box Rail design protects electricians from high-voltage shock hazards.
• Box rail geometry eliminates lateral twisting and side rail deflection during ascent.
• Slip-resistant aluminum Tri Rung treads provide comfortable standing surfaces during long shifts.
• Heavy-duty extruded aluminum locks secure the fly section on the AERO Extension Ladder without slipping.
• Dual-action feet pivot for flat concrete or dig into soft dirt.
• Protective guide brackets ensure smooth operation when extending the fly section.

Dynamic Load Testing Telemetry

Load testing confirms the structural fiberglass box rails and aluminum Tri-Rungs withstand 375 lbs of static downward pressure without deflection or lock failure. Electrical insulation telemetry verifies zero current transfer across the fiberglass rails at 25000 volts. The box rail design reduces lateral twist by 40 percent compared to standard channel rails under 500 lbs of dynamic lateral force. The slip-resistant Tri-Rungs maintain a 0.85 coefficient of friction under wet conditions. Rope and pulley mechanisms lift the fly section smooth under full load.

Field Operation Usability Directives

Workers position the ladder against the building or utility pole, ensuring the base is secure on level ground. The rope and pulley system hoists the fly section into place. Do not overextend the ladder past the safety stops, climb above the top three rungs, or use on ice.

• Inspect the Fiberglass Box Rail for cracks or delamination before each work shift.
• Check aluminum Tri Rung locks and pulley ropes for wear every 30 days.
• Wipe grease and mud off the aluminum treads after each use.
