This is a very sturdy, commercial grade, four section ladder that is used in the window washing industry. With all four sections, the ladder is 23 feet long. The length of the four sections is as follows; the base is 6 feet , the first mid section is 7 feet, the second mid section is 6 feet and the top section is 7 feet. This ladder is a must for the jobs you do on tall buildings !! The price for a new equivalent ( from " Squeegees" on the internet ) is $1350 American, so this is a sweet deal.
