I've got a job where about 20 windows are at 100 feet.
I bought the Extreme 47' and 10 extension sections to give me a pole length of 97' (against Alex's recommendation I should add)
I lost my nerve after I attached the 7th extension and didn't think it was safe to go any higher, so didn't.
I'd been quite open with the site manager about what i was thinking of doing and that it was an experiment.
He was fine with it, we now clean the top 2 floors how they always used to be cleaned-from the inside reaching out.
I don't really like using the Extreme with more than 5 extensions because of the whip in it but 4 sections down is a breeze.
I used to use the Ionic Ergolite3 72' so anything is an improvement on that.
For those that don't know, it was about 9 feet long closed, had about a 3 inch diameter and was about 10kg in use from memory. As somebody else has posted you had to butt it into the base of the building, fully extend it and 'walk' it up the wall. A particular 'favourite' was a job we did in Nottingham City Centre where we had to stretch it across 6 (3 going each way) lanes of traffic in the very short time that the traffic lights were red! Started about 4am so there was minimal cars but the taxi drivers were always hurling abuse
I used the Ultimate with 14 sections but didn't get on with the control bars, s that 79 feet?
The girth of the 14th section wasn't comfortable for any length of time. Though i didn't use it for very long.
I'd be interested to hear of anyone using the control bars and how long it took to get used to them...
