Ladders of various types are in only about every home and work place. There are extension ladders, step ladders, rolling ladders, fixed steel ladders, work platforms and different types of specialty ladders to fit certain needs. Extension ladders are commonly know among everyone. The majority of the extension ladders are made of metal or fiberglass. Aluminum ladders offer lighter weights which can make them easier to use for the average person. Most extension ladders appear in heights ranging from 16 - 60 feet, and excess fat capacities of 250 - 375 pounds. The weight capacity rating can be a tad miss leading considering almost all of the best quality ladders like Werner ladders are test to four times the declared capacity. Fiberglass extension ladders are the option you want to choose if you are going to be doing electricity work or working close to electrical sources. The fiber-glass frame will not conduct electrical power keeping the user safer by electrical injuries. Another feature that is a plus in extendable ladders are D steps. This means the top side of this rungs are flat. This provides you with the user more secure footing while climbing up and down the step ladder.
