Extending or telescoping ladders, which make up one or multiple sections which extend upward, either doubling or tripling the available length of your standard ladder. They're not self-supporting so they'll have to be leaning against some sort of supporting structure, usually the side of a building. They're great for works like painting homes as often you can reach right up to the top of the house you're working on without clumsily making your way back down. There is a limit though to what kinds of work you can perform with a telescoping ladder though. It's not something you'd really want to do if you were doing anything other than painting houses.
There are many kinds of telescoping ladders and some of the most popular ones include those made of aluminum, fiberglass and steel. For the aluminum telescoping ladder, the material is usually either forged or stamped. The aluminum is lightweight so it's easy to carry; however the weight of an aluminum ladder can cause it to tip over. Fiberglass telescoping ladders are sturdier but tend to be less lightweight so they tend to have a shorter practical lifespan.
Another thing to consider is how stable a ladder is when you're carrying it up or down. Most telescoping ladders seen on choicemart, have an extension, where you snap it onto the side or rear of your vehicle which increases its stability even further. They're designed to stay put when you're fully extended to the point that at least three feet of additional weight are required to keep it upright.
One thing customers said about fiberglass was that it tended to shake on you when you were extending it. Most extension ladders were a bit less stable when you were carrying it up compared to a steel or aluminum one. You could tip the fiberglass pole over and it would move a bit but other than that, customers said that they were pretty much the same in terms of performance when it came to tip-over stability. Steel tends to tip over more because it's more heavy, especially when you're fully extended.
One thing customers said about steel when it came to anodizing was that the finish tends to scratch after years of use. Anodized finishes generally resists rust so this isn't a major issue with most people. The average weight of anodized finish models was about 36 pounds so it isn't too heavy to lug around.
Aluminum weighs slightly less than fiberglass and is a bit stronger. It's more lightweight than steel but is still very sturdy. Customers said that when using an extension ladder with this type of telescoping handle, they don't have to worry about the ladder toppling over or injuring themselves. They said the aluminum is strong enough to hold the heavier person's weight without any problems. The lightweight properties of aluminum make it great for when people are carrying heavier items like boxes or books. Most of these extension ladders weigh about three-hundred pounds.
There is nothing about these models that makes them different from one another. One just has to look at the outside of the pole to determine if it is a fiberglass pole or aluminum pole. Both materials are light enough to be carried by one's hands. The little Giant extension ladder has a light weight but doesn't have the same durability as others.
Overall, all three models were described as good performers. Each has a distinct advantage over the others based on price and durability. Most buyers said they would definitely purchase an extension ladder made of this material if they needed help with reaching higher places. The lightweight feature, easy storage, and strength were three of the biggest advantages they had. If a person only occasionally uses their ladder, then the cheaper versions might be a good choice, but they would not want to purchase one of these models if they were going to use it every day.
