Comparing The prices This model to Model #D6240-2

This ladder is $680.97 the only difference I see is in the title, It says 1AA duty rating. If you scroll down to the "DETAILS" on this ladder it shows 1A-300Lbs rating. The $478.59 fiber glass 40' ladder says its a 1A duty rating.When you scroll down to "DETAILS" it is giving the exact same rating (1A-300Lbs) rating. Can someone tell me what the difference in buying the Warner 40'ft Fiberglass ex. ladder $680.97 1AA duty rating is to the Warner 40' Fiberglass ex. ladder $478.59 1A duty rating is if under "DETAILS" they are classified exactly the same (as 1A-300lbs) Thank You for you help

Rated 5 out of 5 by from Best ladder I purchased this model ladder when I was 21 years old to climb power poles for catv. Then used for construction and now been using to climb roofs. I am now 52. This ladder when on a truck and wind blowing does not make the whining sound that others ladders do. I will be purchasing a new ladder for myself after 30+ years of use. It will be the same model.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.
