Werner 20 Ft. Type IAA Fiberglass Leveling Extension Ladder

Description

Does uneven ground force your electricians to use dangerous wood shims under extension ladders? The Werner 20 Ft. Type IAA Fiberglass Leveling Extension Ladder features integrated base levelers. You climb safely on sloping terrain. However, this 20-foot extension ladder cannot reach commercial roofing exceeding 19 feet of working height.

Werner builds this extension ladder with non-conductive fiberglass side rails and heavy-gauge aluminum D-rungs. The base features factory-installed LeveLok leveling legs that adjust up to 8.5 inches to stabilize the ladder on uneven ground. Heavy-duty extruded aluminum locks secure the fly section. The ladder boasts a massive 375-pound Type IAA duty rating. Protective guide brackets and dual-action feet ensure secure placement on hard concrete or penetrable soil.

• Factory-installed LeveLok legs adjust up to 8.5 inches for uneven terrain.
• Slip-resistant aluminum D-rungs provide comfortable standing surfaces during long shifts.

• Mar-resistant end caps protect building siding from scratches and dents.

Dynamometer Bench Testing Load Telemetry

Load testing confirms the structural fiberglass rails and aluminum D-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 LeveLok base legs lock secure under 500 lbs of dynamic downward force, preventing ladder shift on 15-degree slopes. The slip-resistant D-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 Maintenance Directives

Workers position the ladder against the wall and depress the LeveLok foot pedals to drop the leveling legs onto uneven 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 fiberglass side rails for cracks or delamination before each work shift.
• Check aluminum rung locks and pulley ropes for wear every 30 days.
• Wipe grease and mud off the LeveLok leg mechanisms after each use.
