DEWALT DXL3020 32-ft Fiberglass Type 1A-300-lb Load Capacity Extension Ladder

Extension ladders require a surface, such as a wall or a roof line, for support. They’re usually available in larger sizes than step ladders, making them a good choice for outdoor projects, like cleaning gutters or painting the outside of a home. Be sure you know your average reach height when shopping for your ladder. Using a ladder that’s too short or tall can hamper the safety and efficiency of your work.

Common ladder materials are Aluminum and Fiberglass. Aluminum ladders are corrosion-resistant, strong and lightweight, making them a durable choice that's easy to maneuver and carry. Aluminum ladders also conduct electricity, however, so don’t use them when working on electrical projects or near electrical lines. Fiberglass ladders are strong and durable. When clean and dry, they don’t conduct electricity and are the right choice for electrical projects and work near electrical lines.
