These ladders have steps on both sides, which really helps if you’re doing something where someone has to climb up and help you, like hanging fans or light fixtures. It has a higher rating (375 lbs) than most other heavy-duty commercial grade ladders. Its exceptional build quality and strength make it pretty much bullet proof. A friend introduced me to these after his painter had left one for him to repair some fallen gutters at his home three years ago. He loved it and bought one. I saw it, loved it and bought one and have been using it ever since.
