Rated 4.4 out of 5 by 10 reviewers.
Rated 5.0 out of 5.0 by Best brand, excelent quality, and a good price! I have no complaints about this ladder I ordered. Home Depot had the best price (nobody locally had it in stock) and a reasonable order time frame. My first project with it was cleaning, repairing, and covering the gutters on my house. The top roof is very high and has a steep pitch so the best and/or safest method to do the job was by ladder (I didn't have one tall enough). The ladder is of great quality and performed perfect and as expected. I am a big guy weighing 250 LBS so I ordered the heavy duty, 375 LBS rated model so I would not have any issue carrying tools and supplies up the ladder with me. My only regret is not ordering the next size up (longer). The tall roof was hard to get a accurate measurement from and I did not consider the extra length to allow for a nice lean from the ground to the house. This one was just long enough but I would be better If I had the extra length. But again, that is my fault as I did not get an accurate measure. I recommend this brand ladder over any other; it is made sturdy and built to last a lifetime. My recommendation if you have never bought a tall extension ladder is to educate yourself about ladders to ensure you buy one that is best for your need. The Manufacturer as a wonderful ladder information FAQ in addition to a guide that will help you select the appropriate model for your needs. June 24, 2014
Rated 5.0 out of 5.0 by 24 Ft Fiberglass Extention ladder H.D. In my 30 years of H.V.A.C. Experience of service work, and new construction, I can honestly say in my opinion "Werner" makes the most durable & dependable ladders on the market. December 10, 2013
Rated 5.0 out of 5.0 by Heavy duty and stable While a bit unwieldy, I cannot expect less for a ladder of this size and weight rating. I was up on my roof in no time and felt secure the entire time. I usually hate getting up on tall ladder, but this one was actually quite pleasant as things go. It bounced a tiny bit, but I never felt in a precarious situation like I have with other ladders I have owned. So if you are a big guy like me and/or carry a lot of gear up a ladder, this ladder will do you well. October 14, 2014
Rated 5.0 out of 5.0 by Great ladder This 20' yellow extension ladder is exactly what I ordered. It's probably a little more heavy duty than what a typical homeowner needs. I needed the 375 lb rating because I carry heavy stuff up and down the ladder. It's very sturdy. It is heavy to lift and position, but, I am willing to trade this inconvenience for the strength of the ladder. All-in-all, I am very pleased with this purchase. February 25, 2015
Rated 5.0 out of 5.0 by If you really want to go UP in the world.... As ladders go this one is 'right up there' so to speak. Lightweight yet strong. At 55 years old and still climbing on roofs I base my ladder selections on quality vs. weight. Naturally I want a good, safe, dependable ladder that will last for years in any weather (as I hope to myself) but lifting it on and off my truck several times a day the lighter the better and this one does it all! My only other requirement is my ladders be independent rung, not through the uprights as that creates a wind tunnel effect and I don't want to go down the road whistling a tune. The construction of this ladder is perfect and is a nice quiet runner at any speed. HD estimated 4 weeks delivery on my order - got it in just over 2 -nice job Home Depot! April 22, 2015
Rated 5.0 out of 5.0 by Ladder for the lil guys! I work in the petroleum & gas industry. The size of employees using this ladder varies. So it was not hard to choose this ladder for not only the weight factor, but for the safety rating as well. The ladder used prior to this purchase doesn't even compare. January 19, 2015
Rated 1.0 out of 5.0 by looked great Friend bought this ladder and the one side had a MAJOR failure causing the ladder to collapse when he was 20+ feet up. VERY VERY lucky not to be dead. DO NOT BUY IF YOU VALUE YOUR LIFE. March 15, 2015
Rated 5.0 out of 5.0 by Well Built The Ladder is well built. I little heavier than I thought, easier to use with two people. I thought the price was a little high but it is what other ladders of that quality go for. I will probably have it for my lifetime so I am sure I will get the return on my investment.
