Questions & Answers

Can I get confirmation that, as a 350 lb man, the 20 ft, 1AA version would be sufficient for me? Also, is the AC78 stabilizer the right one to use in conjunction with this ladder and also be sufficient for my weight?

Answer This Question

The 375 pound rating for an IAA would need to include yourself and anything you are carrying onto the ladder. The AC78 is the only Werner stabilizer for that particular ladder.

          All of these ladders show their height. Is that height dimension with the ladder extended or unextended?

          Answer This Question

          The measurement is if you took each separate part of the extension ladder and added up their height. When the extension is fully open, as an example using the 16' fiberglass D-Rung extension ladder, when fully extended, it is approximately 13' 2.4" in height.

                      Does this ladder come with the leveling legs, and the cable hooks? If yes, cool can't wait to get one, if not, why is it advertised this way?

                                  Ladder is constructed/built solid, but delivered with some really deep scratches/scrapes, and looks as if it fell off a truck before I got it. A $600 ladder should at least come packaged better than a couple pieces of taped-on cardboard edges, which I assume ripped off early during the transport phase, as it arrived with these pieces hanging off. I needed the ladder for a job, so had to take what I got.

                                  28ft ladder
                                  Purchased this ladder online due to having to drive an hour to the store to pick it up. I’d say for $50 shipping, I’d expect I’d to be a little better taken care of. The ladder was damaged and scratched all over. The packaging that it was wrapped in was missing or damaged. I had purchased one prior and my delivery was canceled due to them breaking it during shipping. No one called and the email came in late. There was no reason why it was refunded or canceled. I had to call HD to figure it out

                                    This is an excellent ladder. It's strong and can easily support a 275 lbs person. It's heavy, but not too heavy. Extending and retracting the ladder is silky smooth once you get the hang of it. The feet are grippy and they can be flipped up so they dig into soil. One of the best things about buying a Werner ladder is the accessories. I also purchased the stabilizer bar and the rubber bumpers (AC19-2). It's worth nothing this is the 2nd Werner ladder I've special ordered from Home Depot. The first ladder had bad rivets, but Home Depot had no problem exchanging it. Be sure to inspect the rivets before taking it home!

                                    The ladder was delayed due to an error on Home Depot’s end. If I didn’t call, I still would not have the ladder.
