Werner Aluminum Extension Ladder - D500 series

This reviews the 24' ladder (21' working length), but most of the review applies to any length...

Product Review:

I now own 11 ladders; a fixed-length ladder, an articulating model, six step ladders (from 2' to 14'), a Werner M13 multi-ladder, and two extension ladders. When available, I buy Type IAA ladders even though the thicker aluminum increases weight, because they are much stronger than even the next lowest rating (Type IA). That's important to someone weighing 270 lbs.

Pros of this ladder:

- sturdy, little flex when you're up high. Type IAA is the highest duty rating (strongest) for any aluminum extension ladder. IAA's hold more weight safely

- the 24' model is pretty easy to move around by myself (see Customer Images for a table with the actual weights of all Werner Aluminum IAA ladders)

- rope/pulley raising lowering mechanism works fine

- ladder sections separate to make two fixed-length ladders

- comfortable if standing on a section that overlaps, since you'll be standing on the inner and outer rung at the same time. Much less comfortable to stand on one rung (rung depth isn't that great) for long periods

- rungs can't twist and are tightly attached

- outstanding heavy-duty shoe design (the rubber/aluminum assembly the ladder rests on)


- a bit uncomfortable if standing for long periods on the rungs if wearing sneakers. When working for long periods, the Wermer AC-18MT auxiliary platform is a comfortable alternative. My old type IAA aluminum extension ladders have 3" deep rungs/steps, but those old-style ladders were heavier per foot of ladder.
