Our take on the Dewalt 20 ft. Fiberglass Extension Ladder Type 1A

The DeWalt 20 ft. fiberglass extension ladder is a Type 1A duty-rated ladder with a 300 lb load capacity and a 17 ft. maximum working length. Fiberglass rails resist electrical conduction, which sets it apart from aluminum ladders of the same size. D-shaped rungs and the extension design make it a fit for tradespeople and serious DIY users working at roof height. It is heavier and bulkier than aluminum rivals, so it suits users who value safety and durability over portability.

Questions and answers

Is this ladder safe to use near electrical lines?
The fiberglass rails are non-conductive, which is why electricians favor fiberglass over aluminum. No ladder makes contact with live wiring safe, so keep clear of lines regardless.
How high can I reach with it?
It has a 17 ft. maximum working length, enough to reach the eaves of most single-story homes. The 20 ft. figure is the full extended length, not the safe working height.
What does Type 1A mean?
Type 1A is a duty rating for a 300 lb maximum load, covering the user plus tools and materials. It is the second-highest common duty rating after Type 1AA.
How does it compare with an aluminum ladder?
Fiberglass is heavier and costs more but does not conduct electricity and tends to feel stiffer. Aluminum is lighter and easier to move but unsafe near live wiring.
Can one person set it up?
Yes, but the fiberglass build is heavy, so raising and extending it solo takes care. A second person makes setup safer, especially at full extension.
What is included with the ladder?
It ships as the ladder itself with its extension rope and pulley. A stabilizer or ladder leveler is not included and is sold separately.
