Werner 20 Ft Type IA Fiberglass Step Ladder

Description

Reaching commercial high-bay lighting and HVAC ductwork requires immense vertical reach without sacrificing platform stability. The Werner 20 Ft Type IA Fiberglass Step Ladder delivers a 20-foot working height rated for 300 lbs capacity. You access high ceilings with secure footing. However, this massive step ladder cannot be set up easily by a single worker.

Werner builds this twin step ladder with non-conductive fiberglass side rails and heavy-gauge aluminum steps on both sides. A molded aluminum top cap holds tools and hardware. The steps feature serrated Traction-Tred slip-resistant aluminum profiles connected via heavy-duty internal steel spreaders. EDGE molded bracing provides enhanced damage protection to the base. The massive 131-pound structure demands two-person handling during jobsite positioning.

Key Features of Werner T7420

Equip your commercial construction crews with this massive twin step ladder to handle electrical drops and HVAC installations in high-bay warehouses. Direct wholesale pricing ensures contractors maintain OSHA-compliant climbing gear.

• A 300-pound Type IA duty rating supports heavy workers carrying tool belts on both sides.
• Non-conductive fiberglass side rails protect electricians from high-voltage shock hazards.
• The 20-foot height provides safe access for commercial 24-foot ceiling installations.
• Twin-step design allows two workers to climb simultaneously from opposite sides.
• Traction-Tred aluminum steps provide slip-resistant footing in dusty work environments.
• Internal steel spreaders prevent ladder collapse during heavy dynamic loading.
• EDGE molded bracing protects the bottom rail from impact damage.

Dynamometer Bench Testing Load Telemetry

Load testing confirms the structural fiberglass rails and aluminum steps withstand 300 lbs of static downward pressure per side without deflection or rivet failure. Electrical insulation telemetry verifies zero current transfer across the fiberglass rails at 25000 volts. The internal steel spreaders lock out to provide a stable 136-inch base spread, preventing lateral tipping under dynamic side-loading. The Traction-Tred steps maintain a 0.85 coefficient of friction under wet and dusty conditions, preventing boot slippage during rapid ascent.

Field Operation Usability Maintenance Directives

Workers unfold the massive ladder using two-person coordination and lock the internal steel spreaders down before climbing to the work height. The twin-step design allows a second worker to assist from the opposite side. Do not stand on the top cap, overreach beyond the fiberglass side rails, or use this step ladder on uneven ground.

• Inspect fiberglass side rails for cracks or delamination before each work shift.
• Check aluminum step rivets and spreader hinges for tightness every 30 days.
• Wipe grease and mud off the Traction-Tred steps after each use.
