After extensive consideration, I purchased this Werner D8220-2ES because safety and longevity were my primary concerns. I could have gotten by with a 200 lb. aluminum Type 3 rated ladder, but felt the 300 lb. fiberglass Type 1A rating would add to the ladder’s overall stability, longevity, and safety. The equalizer level adjustment is an incredibly useful safety feature, especially since my home is built on gently sloping property. I added the AC78 stabilizer, which makes this ladder absolutely rock solid at any height. I wasn’t sure how easy this commercial, heavy-duty ladder would be to manipulate for a single person, but as a 61 year-old, I can easily lift the ladder over my head, walk it around my home, and swing it into any position against my home with no problem at all. With the attached AC78 stabilizer, climbing up the ladder feels like I am walking up a concrete staircase. This ladder is a gem.
