The stepladder is likely to be more stable, but will not work on stairs or close to walls like the Little Giant. The highest I have seen listed in catalogs is 14' to the platform.Ī good 20' stepladder probably costs as much as the 21' Little Giant. If I needed to get to only 20 feet, I would get a platform ladder, which has a fairly wide platform about 2' from the top, and a railing around 2 sides of the ladder at the top. I have spent many hours atop these ladders, and feel more comfortable on them than on a high stepladder. You loop your legs over the extension, and straddle the extension. It is also used as a ladder, especially in theaters. The extension trestle is an "A" ladder with an extension section in the middle, and was originally designed to hold scaffold planks. If you really need that height, you have at least two other alternatives: A 20 foot stepladder, which will get your feet to about 18, or an extension trestle. Given the size of the rungs on the Little Giant, I am not sure I would feel comfortable that high up on those rungs. You can probably reach to about 6', so you can reach 25'. The highest you can stand on a 21' ladder is about 19'. These are harder to stand on than stepladder steps.Īs a safe and practical matter, you can stand 2 feet below the top of a stepladder. Regular stepladders have treads to stand on, while the Little Giant (and the Jaws) have rungs, like those used on an extension ladder.
The regular stepladder is likely to be more sturdy. The Little Giant has a hinge at the top, and what looks like a piece of rope partway down.
The regular stepladder has a locking bar that holds the ladder together, which is located some distance down the ladder for rigidity. There are a couple of differences between a Little Giant ladder and a regular stepladder. It is heaver than my 8' wood ladder however. My 8' ladder folds up small enough to fit in a car trunk, and is both a step ladder and an extension ladder. I like my Jaws ladder, and have used it a lot. This is a quick hinge to lock, but there will always be a bit of play in the joint at the top. The holes for the pin have to be a bit bigger than the pin, so that the pin will be easy to enagage. The Little Giant uses a hinge that is locked by a pin on each side. This construction results in a slow operating hinge, but one that is always tight. The teeth are tapered, and the two halves are drawn together by a bolt and nut with a handwheel. The Jaws uses what looks like a jaw clutch, with probably 6 teeth and spaces.
The difference between the Little Giant and the Jaws is how the hinge is locked. That is the real name, and made by a company in Canada. The Skyscraper M17 exceeds all OSHA and ANSI standards and is rated to hold up to 180 Kg.I have a ladder made by a competitor, "Jaws".Replace much more expensive power lifts, scaffolding systems with a ladder that is much easier to use, store, and maintain.Take this ladder where no other 21-foot A-frame can go, including tall staircases, stadium seating, theatres, and other sloping or uneven surfaces.The SkyScraper Model 21 is fully adjustable, reaching as high as 6.40 metres while storing in only 3.53 metres. The SkyScraper can handle virtually any industrial job: it is made of heavy-wall, aerospace-grade aluminium and is rated to hold up to 180 Kg. And because it’s portable, the SkyScraper can be used in places where a motorized lift or bulky scaffolding simply can’t go. The SkyScraper is especially useful when working around obstacles like benches and stadium seating. Now you can reach the highest spots in churches, auditoriums, gymnasiums and in specialized industrial settings. When you have to reach extreme heights, the Little Giant SkyScraper is the economical and safe replacement for expensive lifts and scaffolding. Little Giant Skyscraper Aluminium Telescopic Ladder 21
