Question: I'm about to work on estimates for a roofing company, will this ladder be fine to use to get on top of most roofs, measure a few things and get off? will it reach?
Document: I needed a ladder for my home inspection business. I wanted something light, durable and could reach 17'. I did some research online and asked a few home inspectors and they all recommended this ladder.The ladder arrived on time and was easy to use. This is a really nice ladder, I highly recommend it if you need a ladder for multiple heights and uses. I have to extend the ladder to full height, it is very sturdy and I don't feel tippy when I'm on the top.
So... I bought this thinking it would come in handy when we needed to reach our super high ceilings (2 storey great room and foyer). And I'm sure it will eventually be useful to reach those high places but for everyday usage, its quite heavy and cumbersome - which is probably a good thing since it means its more stable when you do need it for high spaces. I purchased another Little Giant ladder for everyday use and its much more practical :)
I have not yet used it as an extension ladder, but as a stepladder, the Little Giant is very stable, and the adjustability makes it possible to use it where a regular stepladder would not work. The drawback for me is that it is very heavy. Even moving it a short distance from one spot to the next while working is a real chore. This is not a ladder I'm going to whip out to change a light bulb!
awesome ladder. i use it anytime i need to get more than 3 ft off the ground. made hanging christmas lights much easier. i'm 6'1&#34; 290lbs btw.
I am a contractor and use Little Giants ever day for the last 10 years. The originals are still kicking around. This unit was purchased for me to use caring it around to do estimates and lite work, its perfect!! It has to weigh 10 lbs less than the one i was caring and at 58 that makes a difference. sturdy and well design.
I do agree that standing on the ladder for any period of time you need hard sole shoes. I did buy the work platform but have not used it. I have used the ladder in the fully extended position to reach and clean a high interior window without an problem.
I purchased this ladder from Amazon as a gift to my boyfriend. We recently moved into our own house and were in need of a good solid ladder. He had been looking at the Little Giant brand for quite some time and wanted to get one but never got around to it.This ladder will easily and solidly reach our second floor roof, it doesn't bounce around like a trampoline like other cheaply made extension ladders. We've also hung bird feeders far up in trees and he has felt safe doing each task.
Stair Work? No problem. I live in a split level home, so I have that two teir staircase that has that tall unused area of wall. Im able to get up there finally and paint, hang crown molding and pictures.I haven't used it yet at full extension for roof work, but will do that in the spring. In the 2 weeks I've owned this ladder, I've been able to get a lot of projects done around the house that would otherwise need multiple ladders for.
Very easy to assemble and use. I'm petite and not very strong and even I managed to assemble for use.
If you own a home or you are in a business that requires a ladder, this is all you need. This ladder does so much it's great. I have used this ladder at work in the US Navy and it's the only ladder system we use for working with aircraft.
