Question: How high is the a-frame in the Alta 22? My fan blades are 11'7" up there!
Document: I bought this to paint my 2 story foyer, ceiling and the stairway walls going up. It worked great and was cheaper than hiring a painter. I bought the big model 22 so I could get to the top of the stairway walls and be able to cut in the ceiling. Worked perfectly.The commercials make it look like you just whip this thing around, up and down, no problem. Not so much. It's very heavy and awkward to switch over from A frame to straight.
This thing is durable, versatile, and high quality. I love it! It does what  6 other ladders do. Best of all, it's aluminum construction allows me to keep it in the rain, and no problem.
A-frame height is 9' total. It has wheels on one side so you can easily pull it around. Pretty easy to adjust to different positions.
I love the sturdy feel of the ladder when used as a step ladder. I also love that I can adjust the height from short ceilings to chandler high lights. It is a little heavy, but the wheels make it easy to move around on one level.
But switching between A frame and straight is similarly awkward. Weight and max extension is the same as the 4 section clicker. It is a lot easier to haul in from the garage also. It folds more compact and is pretty easy to carry around.
Though I like this ladder, it's title and specs are misleading, I have a 21ft ceiling, but did not need it at full length until past return duration. Now it cost me, since i need a second ladder.
The ladder showed up fast and we have windows on our stairs the ladder works perfect to clean them we also are able to change the fire alarm battery's in the vaulted ceilings
Spring latch for ladder extension fell out on 1st pull. Only held in place by plastic cap. And plastic cap was not fully seated because of excess weld under cap. Stay tuned for company's response and how much extra shipping fees will cost for replacement. Update: Little Giant service was excellent, they agreed the weld was not up to their standards and replaced it and paid for all shipping charges.
I had to do a lot of reconfiguring to get the job done and it was time consuming. I had to clean up a lot of stuff because the awkward nature of the reconfiguration took a lot of space and wasn't always smooth. Didn't want paint everywhere.The mechanism works great. I had one of those 4 section reconfigurable ladders that clicks from angle to angle in each of the four sections. This works much better than that for most things.
I am no expert on the subject of ladders but I know I wanted something small that can expand and had the ability to do unique heights levels. We this one does exactly what I need it to do. My only concern and a minor one at that is it is heavy. I have purchased some of the extra components and they come in handy.
