　　Fiberglass extension ladders are designed for high-reach tasks that require height beyond the capabilities of step ladders. They consist of two or three telescoping sections (base and fly sections) that slide up and down using a rope-and-pulley system, allowing users to adjust the height according to their needs . These ladders are non-self-supporting, so they must be leaned against a stable structure like a wall or utility pole.

　　Key Features: Non-conductive fiberglass rails, heavy-duty rung locks (such as Max Lock systems) to prevent section slippage, swivel safety shoes for uneven surfaces, and adjustable increments (usually 12 inches) . Heights range from 16ft to 40ft (extended), with load capacities up to 375 lbs (Type IAA) . Some models come with additional attachments like cable hooks or pole grips for securing to utility poles .

　　Common Applications: Outdoor electrical work (e.g., power line maintenance), roof inspections, construction projects, and gutter cleaning. Widely used by electricians, utility workers, and construction professionals .

　　Popular Search Terms: “16ft fiberglass extension ladder,” “insulated fiberglass extension ladder OSHA compliant,” “300 lb fiberglass extension ladder”; Russian: “стеклопластиковая выдвижная лестница 5м,” “изоляционная стеклопластиковая выдвижная лестница соответствующая OSHA,” “стеклопластиковая выдвижная лестница 136 кг.”

　　3. Fiberglass Telescoping Ladders (Collapsible Ladders)

　　Fiberglass telescoping ladders are a modern, space-saving alternative to traditional extension ladders. They feature multiple nested sections that retract into a compact size for easy storage and transportation, making them ideal for professionals who need to carry ladders in vehicles or work in tight spaces .

　　Key Features: Lightweight yet durable fiberglass construction, one-touch locking mechanisms for each section, slip-resistant feet, and load capacities up to 330 lbs (150 kg) .
