I bought one of these 300lb weight rated aluminum ones on a whim, Lowes was clearing them out for about $135 with vets discount. They make them in fiberglass with a 375 lb weight rating, but I didn’t want that. They also wanted about 220 for those ones.
I can say it is really functional. I wanted something that would take the place of my easy to carry A frame, allow me to get a little higher, and lean on houses when painting or use on higher decks. Fits the bill. It can get you to the roof of a one story (tried it out on my garage) as long as it isn’t a raised area (I’d say mine is about 10’ off the ground and I had rungs above the gutterline). I also used it in my stairway at my house, it worked, but it doesn’t have the working height (or weight) of say a full blown multifunction.
Just thought I’d give a quick take on it if someone was looking. You still need an extension ladder for most jobs, but I think the A frame is leaving the trailer now.
